ITEM 1.  FINANCIAL STATEMENTS




                            AUREAL SEMICONDUCTOR INC.

               INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                   (Unaudited)

      The Interim Condensed Consolidated Financial Statements of Aureal
Semiconductor Inc. (the "Company") have been prepared by the Company, without
audit, pursuant to the rules and regulations of the Securities and Exchange
Commission. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principals have been omitted pursuant to such rules and regulations. The
disclosures included in the Interim Condensed Consolidated Financial Statements
should be read in conjunction with the Company's audited financial statements at
December 28, 1997 and the notes thereto included in the Company's 1997 Annual
Report on Form 10-K.

     The preparation of financial statements in conformity with generally
accepted accounting principles and pursuant to the rules and regulations of the
Securities and Exchange Commission requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

     The Interim Condensed Consolidated Financial Statements reflect, in the
opinion of management, all adjustments (which include only normal recurring
adjustments) necessary for a fair presentation of financial position, results of
operations and cash flows for such periods. The results of operations for the
fiscal quarter ended June 28, 1998 are not necessarily indicative of the results
that may be expected for any subsequent quarter or the entire fiscal year ending
January 2, 1999.

AUREAL SEMICONDUCTOR INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


1.   THE COMPANY AND RECENT FINANCIAL EVENTS

     Aureal Semiconductor Inc., together with its subsidiaries Crystal River
Engineering, Inc. and Aureal Semiconductor Limited (combined, the "Company")
specialize in the design and marketing of audio semiconductor technologies for
use in both the PC and consumer electronics markets. Crystal River Engineering,
Inc. ("CRE"), founded in 1987 and acquired by Aureal in 1996, has been a pioneer
in the development of 3D audio technologies. Aureal Semiconductor Limited,
located in Hong Kong, was established in the first quarter of 1998 as a sales,
technical support and field engineering office. The Company's business involves
both the development and sale of audio processing semiconductor chips, as well
as the licensing of technology which is designed to define and develop advanced
audio standards in the marketplace. The Company's stock symbol on the OTC
Bulletin Board is AURL.

     During March 1998, the Company completed the sale of $5 million of Aureal
Series A Preferred Stock.

     On June 5, 1998 the Company completed three financing transactions, which
had the combined effect of increasing the Company's borrowing capacity and
providing additional equity for the Company. The transactions included the
following:

o    The sale of $5 million of Aureal Series C Preferred Stock to DDJ Capital
     Management, LLC. Approximately $3.66 million of the offering was used to
     pay down the outstanding balance on the existing Line of Credit. The
     remaining $1.34 million was utilized for working capital purposes.

o    The remaining balance of $31.5 million on the existing Line of Credit was
     exchanged for 39,375 shares of Aureal Series B Preferred Stock.

o    A new $40 Million Revolving Credit Facility was established with Goldman
     Sachs Credit Partners LP ("Goldman Sachs") and the Technology Finance
     Division of Transamerica Business Credit Corporation ("Transamerica").

     In addition to the above financing transactions, on June 26, 1998, the
Company completed the sale of $1 million of Aureal Series C Preferred Stock. The
proceeds of the offering were utilized to pay down outstanding borrowings under
the Credit Facility.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Presentation

     The Interim Condensed Consolidated Financial Statements of Aureal
Semiconductor Inc. have been prepared by the Company, without audit, pursuant to
the rules and regulations of the Securities and Exchange Commission. Certain
information and footnote disclosures normally included in the financial
statements prepared in accordance with generally accepted accounting principles
have been omitted pursuant to such rules and regulations. The disclosures
included in the Interim Condensed Consolidated Financial Statements should be
read in conjunction with the Company's audited financial statements at December
28, 1997 and the notes thereto included in the Company's 1997 Annual Report on
Form 10-K.

     The Interim Condensed Consolidated Financial Statements reflect, in the
opinion of management, all adjustments (which include only normal recurring
adjustments) necessary for a fair presentation of financial position, results of
operations and cash flows for such periods. The results of operations for the
fiscal quarter and two quarters ended June 28, 1998 are not necessarily
indicative of the results that may be expected for any subsequent quarter or the
entire fiscal year ending January 2, 1999.

     The preparation of financial statements in conformity with generally
accepted accounting principles and pursuant to the rules and regulations of the
Securities and Exchange Commission requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

     Inventories

     Inventories are stated at the lower-of-cost-or-market value on a
weighted-average costing method. The Company does not consider any inventory to
be raw material since the Company's point of purchase is for fabricated silicon
wafers or finished silicon dies. Net inventories at June 28, 1998 and December
28, 1997 consist of the following, in thousands:

                                        ======              ======
</TABLE>

     Property and Equipment

     Property and equipment are stated at cost and depreciated utilizing the
straight-line method over their estimated useful lives (one and one-half to five
years). Fixed assets with approximately $1.4 million in gross value and zero net
book value were retired during the first quarter of 1998 as they were determined
to no longer be in use.

     Revenue Recognition

     The Company's major sources of revenue consist of sales of proprietary
design, advanced audio semiconductor chips, and licensing of related audio
technologies. Revenue is recognized upon shipment for product sales. Software
licensing revenues are recognized upon shipment of licensed product if a
non-cancelable contract has been signed, the fees are fixed and determinable,
collection of the recognized fees is reasonably assured and there are no
remaining significant obligations.

     Concentration of Financial Instrument and Credit Risks

     Financial instruments, which potentially subject the Company to
concentration of market risk, consist primarily of the Company's line of credit.
This market risk on the line of credit relates to changes in the prime lending
rate, as the line of credit bears interest rates which fluctuate with changes in
the prime lending rate.

     Credit risk for the Company consists primarily of trade receivables. Most
of the Company's trade receivables are the result of sales to foreign companies.
Concentration of credit risk is limited by the use of commercial letters of
credit for many of these international customers. Additionally, the Company has
established an allowance for doubtful accounts based on the credit risk of
specific customers.

     Valuation of Warrants

     In June 1998, the Company issued 1,350,000 warrants ("Credit Facility
Warrants") to purchase the Company's Common Stock to the lenders under the
Company's new Credit Facility (see Note 4). The fair value of the Credit
Facility Warrants was estimated to be $1.8 million. Amortization of the $1.8
million asset, as additional interest expense over the two-year life of the
Credit Facility commenced in June 1998 at the rate of $0.23 million per complete
fiscal quarter.

     In 1997, the Company recorded the estimated fair value of warrants issued
to related parties in association with both the amendment of the line of credit
("Debt Warrants"), and the sale of common stock ("Equity Warrants"). The fair
value of the Debt Warrants and the Equity Warrants were estimated to be $5.0
million and $1.5 million, respectively. Amortization of the $5.0 million asset,
as additional interest expense over the life of the loan, commenced in August
1997 at the rate of $0.75 million per quarter. With the conversion of the loan
in June 1998, into preferred stock of the Company, the remaining balance of the
Debt Warrant valuation was eliminated as part of the net book value of the debt.

     Loss Per Share

     SFAS No. 128 "Earnings per Share" requires that the calculation for basic
earnings per share ("EPS") exclude the dilutive effect of common stock
equivalents in the calculation for basic net income (loss) per share. Diluted
EPS under SFAS No. 128 is calculated using the weighted average number of common
shares and common stock equivalent shares outstanding during the period. Common
equivalent shares are computed using the treasury stock method for outstanding
warrants and stock options. Common equivalent shares are excluded from the
diluted EPS computation only if their effect is anti-dilutive. No common stock
equivalents were included in the calculations for any fiscal period presented,
as, due to the net loss position, any affect would be anti-dilutive.

     SFAS No. 130 "Reporting Comprehensive Income" was adopted by the Company in
the first quarter of 1998. SFAS No. 130 requires companies to report a new,
additional measure of income, however the Company has no material items of other
comprehensive income in any period presented.

     Amortization of Intangibles

     At December 31, 1994, upon its emergence from Chapter 11 Bankruptcy
Protection, the reorganization value of the Company in excess of its net assets
generated a $44.1 million intangible value that was classified as a
reorganization asset in the consolidated balance sheet of the Company
("Reorganization Asset"). The value of the Reorganization Asset was reduced in
the second quarter of 1995 as the Company exited the retail products business.
The net remaining Reorganization Asset was amortized at the rate of $625,000 per
quarter through 1997, and was completely amortized as of December 28, 1997.

3.   ELIMINATION / CONVERSION OF PREVIOUS LINE OF CREDIT WITH RELATED PARTIES

     On June 5, 1998, the Company completed two transactions with the combined
effect of fully paying down the entire outstanding balance and eliminating the
Company's previous line of credit with related parties.

     The sale of 500 shares of Aureal Series C Preferred Stock (the "Series C
Preferred") for $5.0 million was made to DDJ Capital Management, LLC. $3.66
million of the proceeds from the sale were used to pay down the outstanding
balance under the line of credit. The Series C Preferred Stock carries an 8%
accretion rate over its three-year term, and provides for conversion to Common
Stock of the Company or redemption at the option of the Company. It is
convertible at the lesser of a fixed value of $2.50 per Common share or a
discount from the then-current market price for the Company's Common Stock at
the date of conversion.

     The remaining $31.5 million balance of the line of credit was exchanged for
39,375 shares of Aureal 8% Series B Preferred Stock (the "Series B Preferred"),
with a face value of $39,375,000, and the line of credit was terminated. The
lenders under the line of credit released their lien on all the assets of the
Company as part of the termination of the line of credit agreement. The Series B
Preferred Stock provides for conversion to Common Stock of the Company at the
rate of one share of Common Stock for every $2.50 face value of Series B
Preferred. The 8% annual dividend, payable quarterly may be paid in cash or in
additional shares of Series B Preferred, at the option of the Company. The
Company has the option to redeem the Series B Preferred at its face value at any
time during its five-year term.

4.   NEW CREDIT FACILITY

     In conjunction with the conversion and elimination of the previous line of
credit, on June 5, 1998, the Company entered into a new $40 million Revolving
Credit Facility with Goldman Sachs and Transamerica. Terms of the new Credit
Facility provide for up to $32.5 million availability for borrowings related to
specific Company accounts receivable, ("Tranche A"), with an additional $7.5
million of availability unrelated to specific collateral requirements ("Tranche
B"). Interest on borrowings under the two-year agreement is at the rates of
Prime plus three percent for Tranche A borrowings and Prime plus five percent
for Tranche B borrowings. The Company is subject to certain covenant
restrictions under the Credit Facility and has paid a $600,000 fee to the
lenders in connection with the initiation of the Credit Facility.

     As of June 28, 1998 the Company was in compliance with all of the covenant
requirements.


                                       9

<PAGE>   10

     Also in conjunction with the establishment of the new Credit Facility, the
Company issued 1.35 million warrants to the lenders under the Credit Facility.
These warrants are exercisable at any time over their five-year life at the
exercise price of $2.156 per share of Common Stock.

5.   PREFERRED STOCK

     During the first half of 1998, the Company issued three series of preferred
stock. The net proceeds from all the preferred stock issuances were used to
reduce the Company's outstanding debt and for working capital purposes. In
March, the Company issued $5 million of Series A Preferred Stock (the "Series A
Preferred"). The Series A Preferred shares include conversion rights to Aureal
Common Stock at the lesser of a $2.50 fixed conversion rate or a variable
conversion pricing dependent upon the underlying price of the Common Stock at
the time of conversion. The Series A Preferred shares bear accretion at an 8%
annual rate over their three-year term.

     On June 5, 1998, the Company sold $5 million of Series C Preferred to DDJ
Capital Management, LLC ("DDJ"). The terms of the Series C Preferred are
virtually identical to the Series A Preferred. On June 26, 1998, the Company
sold an additional $1 million of Series C Preferred to non-affiliates.

     Also on June 5, 1998, the Company exchanged 39,375 shares of Series B
Preferred for the entire $31.5 million outstanding balance of the Company's
previous line of credit. The Series B Preferred bear a face value of $1,000 per
share and an 8% annual dividend rate. The dividends may be paid in cash or in
additional Series B Preferred shares, at the option of the Company. The $10.7
million difference between the fair market value of the Series B Preferred
shares and the net book value of the exchanged debt (less unamortized fees
associated therewith) was charged directly to accumulated deficit at the time of
the transaction.

     Accretion related to the beneficial conversion features of the Series A
Preferred and the Series C Preferred, and the dividend/accretion rate of 8% on
all three series of preferred stock totaled $1.4 million in the second quarter
of 1998.

6.   INCOME TAXES

     The Company was not required to provide for income taxes in the first two
quarters of 1998 or 1997 due to its net operating losses. No tax benefit has
been recorded for the losses due to the uncertainty as to the realizability.

     At December 28, 1997, the Company had available net operating loss
carryforwards ("NOL's") of approximately $285 million to reduce future taxable
income. The NOL's expire on various dates through 2012. In connection with the
adoption of fresh start accounting, any tax benefit resulting from the use of
the NOL's generated prior to the bankruptcy plan confirmation in 1994 will be
applied as a direct addition to stockholders' equity.

OVERVIEW

     The Company's objective is to be a leading supplier of high quality,
advanced audio solutions to both the PC and consumer electronics marketplaces.
The Company's operating strategy combines the development and sale of audio
processing semiconductor chips with the licensing of technology to strategic
partners in order to define and develop advanced audio standards in the
marketplace. This strategy encompasses the following primary elements:

o    Create value in the Aureal and A3D logos - Aureal is working to establish
     consumer association between the Aureal and A3D brand names and high
     quality audio. This high quality branding strategy can be utilized on
     multiple components of an entire audio solution in the PC arena.

o    Offer low-cost PC audio acceleration - Aureal continues to develop and
     offer high-feature audio accelerator chips at prices competitive with
     lower-featured offerings from other manufacturers. In addition, the Company
     is currently expanding its PC product offerings in response to the evolving
     market for audio and audio communications components. Both audio cards and
     audio communications combination cards are being developed for
     distribution. This expansion of the Company's business model allows Aureal
     to approach the PC market with a complete spectrum of audio components
     targeted to provide solutions at various feature/price points in the
     market.

o    Provide integrated audio components to the consumer market - Aureal is
     developing devices targeted to the consumer electronics marketplace which
     provide lower system cost through integration of digital, analog and other
     audio system functions.

     On July 15, 1998, Diamond Multimedia Systems, Inc. ("Diamond") and the
Company jointly announced that they had entered into a strategic alliance to
develop and market next-generation audio solutions for the PC marketplace. Under
this agreement, Diamond will utilize Aureal's Vortex and A3D audio technologies
exclusively for products sold under Diamond's award-winning "Monster Sound" PCI
audio accelerator brand.

     On June 15, 1998, the Company announced that Compaq Computer Corporation,
the world's leading personal computer company, would begin featuring Aureal's
A3D Interactive 3D audio technology on its new line of Presario desktop
computers. Compaq's marketing materials, including point-of-sale displays in
retail stores and website presentation have begun to actively support Aureal's
A3D technology.

     In April 1998, the Company introduced A3D 2.0, a significant enhancement to
the existing version of A3D that was originally introduced in September 1996.
A3D 2.0, which is incorporated in a growing number of PC game titles, is
backward compatible with the original A3D technology. A3D is currently
incorporated into a number of major PCs (including computer lines from Dell
Computer Corporation and Compaq), as well as a number of PC add-in audio cards
under various brand names. The new A3D 2.0 includes Aureal Wavetracing
Technology (which enables real-time acoustic reflections, reverb and occlusion
rendering features), more 3D sources, a higher sample rate and larger
Head-Related Transfer Function (HRTF) filters. Together, all of these feature
enhancements provide for improved three-dimensional rendering of audio for
interactive applications.

     Also during the first half of 1998, key design wins for the Vortex AU8820
and A3D were announced and chip sales in volume were commenced. The AU8820 is
currently implemented in sound cards utilized or marketed by Dell Computer
Corporation, Turtle Beach Systems, Aztech Systems Ltd. and TerraTec Electronic
GmbH. These customers, in addition to Compaq, are actively promoting Aureal's
A3D technology.

                                       11
<PAGE>   12



     Early 1998 marked the first shipments of audio semiconductor chips by
Aureal after two years of development work in the digital audio design area.
Many of the audio sound card applications utilizing the Vortex AU8820 chip are
based on Aureal's card reference design and have won widespread acclaim as well
as numerous awards from various PC publications. In addition, Aureal's A3D
Interactive audio technology has been widely recognized as the industry standard
for three-dimensional sound presentation. Aureal's Vortex AU8820 PCI-based
digital audio processor chip is a feature-rich audio solution designed for the
PC. In conjunction with Aureal's A3D three-dimensional audio technology, the
Company is offering an audio solution for the PC that takes advantage of the
benefits of PCI technology. The Company believes that the market for PCI audio
is expanding rapidly, and will be a significant market by year-end 1998.
Contributing to the move from ISA-based to PCI-based audio systems for PCs are
the requirements put forth by both Microsoft Corporation and Intel Corporation
relative to Windows qualifications.

     With announced "design-wins" including Dell Computer Corp. (utilizing sound
cards incorporating the AU8820 chip) and Compaq Computer Corporation (A3D
implementation on the Presario line of desktop PCs), Aureal technology has begun
to appear in market-leading PCs. Aureal's A3D technology is also gaining
acceptance from PC game developers, and is currently supported by a number of
major game developers including Activision, Lucas Arts, Interplay, GT
Interactive, Broderbund, Electronic Arts, Sierra On-Line and Ubi Soft. Many of
these developers, as well as PC hardware manufacturers are working with Aureal
to support A3D and Aureal brand recognition through use of the Aureal and A3D
logos on packages and advertisements.


RESULTS OF OPERATIONS

     Net Sales

     Net sales for the second quarter of 1998 were $3.4 million, compared to
$3.6 million in the previous quarter and $0.7 million in the second quarter of
1997. Year-to-date revenues for 1998 of $7.0 million represent the sale of
several hundred thousand AU8820 chips, along with minor revenues from technology
licensing.

     In addition, with the July 1998 announcement of the strategic alliance
between Aureal and Diamond, Aureal anticipates commencement of audio board sales
in the third quarter of the year. This will allow the Company to offer both chip
and board level products to various segments of the PC market. The Company
believes that this expansion of product categories will allow Aureal to better
address the needs of a broader cross section of the market over time.

     Gross Margin

     Gross margin rose from 22% in the first quarter of 1998 to 41% in the
second quarter as the AU8820 product moved from initial ramp-up into higher
volume production. Cost reductions associated with the higher production levels
and higher yield from silicon wafers both contributed to the margin improvement.

     Gross margin percentages in the prior year were significantly higher,
although on limited revenues, as the majority of such revenues were technology
licensing based. The Company does not anticipate that license revenues will be a
significant portion of overall revenues in the future.

     Gross margin percentages could vary and potentially be reduced on some
card-level products that the Company anticipates selling in future quarters.

                                       12
<PAGE>   13



     Research and Development

     Expenditures for research and development continue to be the most
significant area of spending for the Company as it allocates significant
resources to create future audio products for both the PC and consumer
electronics markets. Spending in this area yields both short-term and long-term
product developments - as the Company looks to continue to bring new and
improved products to the audio forefront. Spending increased $0.3 million from
the first quarter to the second quarter of the year ($2.6 million to $2.9
million) as prototype runs of the Company's newest semiconductor product were
commenced during the second quarter. In addition, the Company has continued to
increase the staffing in the research and development area, both with employees
and some specific project contract work. Year-to-date expenditures in this area
increased from $3.0 million in 1997 to $5.5 million in 1998, and have generally
increased each quarter over the last two years as development efforts on both
software and hardware based technology have expanded.

     The Company expects that the level of spending on research and development
will fluctuate, but is not expected to decline significantly in absolute dollars
in future periods.

     Selling and Marketing

     Selling and marketing expenses for the second quarter of 1998 were $1.6
million, an increase of $0.3 million over the previous quarter. This increase
over the first quarter of the year is primarily attributable to expenses
incurred to design and launch an advertising campaign designed to increase the
visibility of A3D to the end-user. This campaign includes media advertising in
various PC-related magazines. The substantial increase in year-to-date
expenditures ($3.0 million in 1998 versus $1.7 million in 1997) is primarily
attributable to costs, including selling commissions, related to the
commencement of AU8820 sales in 1998.

     General and Administrative

     General and administrative expenses for the second quarter were $0.8
million, flat with the level of expense in the first quarter. Quarterly and
year-to-date expenses ($1.7 million) rose from the prior year ($0.6 million and
$1.2 million, respectively) due primarily to increases in recruiting and
employment consulting expenses as the Company has added significant staff in the
first half of this year.

     Amortization of Reorganization Asset

     The Reorganization Asset originated pursuant to the Company's valuation
upon its exit from bankruptcy protection in December 1994, whereby the fair
value of the Company exceeded its net assets by $44.1 million. The
Reorganization Asset value was fully amortized at year-end 1997 (at the rate of
$625,000 per fiscal quarter, during 1997).

     Interest Expense

     Interest expense for the first half of both years consisted primarily of
interest on the line of credit at the rate of prime plus 5%. The expense in 1998
($2.0 million year-to-date, $1.0 million for the second quarter) increased over
the prior year ($1.2 million year-to-date, $0.6 million for the quarter) as the
balance under the line of credit grew over the period. During 1997 and 1998
to-date, the line of credit has been a major source of working capital for the
Company, and has expanded over that time. Proceeds from the sale of equity
capital over that time period have been utilized periodically to pay down the
balance of the debt.

     With the pay down and elimination of the TCW line of credit in June 1998
through the exchange for Series B Preferred Stock of the Company, the interest
expense is expected to decline significantly. The new Credit Facility with
Goldman Sachs and Transamerica carries a lower interest rate than the prior line
to the extent borrowings are based on eligible accounts receivable borrowing
availability.

                                       13
<PAGE>   14



     Amortization of Debt-Related Warrants

     In August 1997, in conjunction with the expansion and extension of the TCW
Line of Credit, the Company issued 3.15 million warrants to the lenders to
purchase the Company's Common Stock. Utilizing the Black-Scholes valuation
method, the estimated fair value of the warrants was determined to be $5.0
million. This value was amortized over the estimated life of the loan at the
rate of $0.75 million per quarter. When the loan was converted in June 1998, the
remaining unamortized deferred costs related to the warrants were netted against
the outstanding loan balance and eliminated as a reduction of the conversion
value of the Series B Preferred shares.

     In connection with the new Credit Facility, the Company issued to the
lenders, in June 1998, 1.35 million warrants to purchase the Company's Common
Stock. The fair value of these warrants was estimated utilizing the
Black-Scholes valuation method as approximately $1.8 million, and is being
amortized over the two-year term of the Credit Facility.

     Other Income

     The Company recognized net other income of $51,000 and $340,000 in the
second and first quarters of 1998, respectively. This compares to $148,000 and
$56,000 in the corresponding quarters of 1997. The income recognized in all
quarters shown was primarily due to various receipts and credits resulting from
favorable resolutions to previously recorded liabilities.

     Income Taxes

     The Company was not required to provide income taxes in the first two
quarters of either 1998 or 1997 due to its net operating losses. No tax benefit
has been recorded for the net operating loss carryforwards due to the
uncertainty as to their realizability.

                                       14
<PAGE>   15



LIQUIDITY AND CAPITAL RESOURCES

     At June 28, 1998, the Company had working capital of $5.6 million and
stockholders' equity of $6.2 million. In quarterly financial statements since
1995, the Company has generally shown negative working capital amounts and
stockholders' deficit amounts. The stockholder equity of $6.2 million is largely
the result of the issuance of preferred stock in the first half of 1998, both
for cash and in exchange for the $31.5 million line of credit balance. These
transactions have resulted in significant Paid-in Capital increases, however the
Company continues to maintain a substantial accumulated deficit developed as
losses have been recorded over the last three years. The Company recognized a
net loss of $5.4 million in the second quarter of 1998 ($10.9 million
year-to-date) as well as direct charges to accumulated deficit of $12.1 million
in the second quarter related to dividends and accretion on preferred stock. Of
that amount, $10.7 million is a one-time charge related to the difference
between the conversion/redemption value of the Series B Preferred Stock ($39.4
million) and the net carrying value of the debt for which it was exchanged
($28.7 million). Other dividends and value accretion related to the Series A, B
and C Preferred Stock resulted in an additional charge of $1.4 million in the
second quarter.

     Working capital used to support operating activities has totaled $18.5
million in the first half of 1998, averaging roughly $3.1 million per month.
This has resulted from the growth of accounts receivable and inventory over that
time, as well as increased operating losses. The Company believes that it will
move closer to generating cash flow from operations as revenues are expected to
grow in subsequent quarters. Such revenue growth is dependent upon the Company's
success in promoting both the Vortex semiconductor design and A3D audio
technology as valuable components to a PC's audio system. The acceptance of PCI
audio (the underlying data-bus technology utilized for both Vortex and A3D) as
the standard for the PC is also key to the Company's immediate growth plans. To
the extent such PCI acceptance and utilization does not materialize as rapidly
as expected, Aureal's growth could be significantly impacted.

     The Company believes that the $40 million Credit Facility, of which $0.4
million was drawn as of June 28, 1998, will provide adequate financial resources
to sustain business for at least the next year. The Company may be required to
seek additional financing to expand its business. There can be no assurance that
the Company will be able to generate positive cash flows in the future or to
obtain financing on favorable terms, if at all.

     Capital expenditures of $1.0 million during the first half of 1998
consisted primarily of hardware and software tools utilized in the Company's
research and development activities. Increased levels of capital expenditures
are anticipated during future quarters of 1998.

RISK FACTORS

     In evaluating the Company's business, certain factors, including those
discussed below and those included in documents previously filed with the
Securities and Exchange Commission, should be considered in addition to the
other information in this Form 10-Q.

     History of Losses and Accumulated Deficit; Expectation of Future Losses

     The Company emerged from Chapter 11 Reorganization in December 1994. Since
that time the Company has incurred losses, in the aggregate amount of $162
million, from (1) operating and eliminating its previous retail products
business in 1995, (2) during the research and development phases of its advanced
audio technologies business operations in 1996 and 1997, and (3) as it began to
sell advanced audio products in the first half of 1998. While the majority of
the Company's revenues in 1996 and 1997 were generated through technology
licensing transactions, the Company anticipates that the majority of its
revenues will come from the sale of audio products in 1998 and future years.
There can be no assurance that the Company will be able to sell significant
volumes of its products in the future, and the Company's ability to attain
profitability or generate positive cash flows is dependent thereon.

     New Technologies and Products Developed with New Technologies

     The Company's success depends on its ability to develop and market new
technologies aimed at advancing the level of audio quality in the PC and
consumer electronics devices. With respect to the PC market, audio technology is
shifting from utilization of the ISA bus to utilization of the more advanced
(higher bandwidth) PCI bus. This change enables advanced digital audio
functionality including positional 3D audio, streaming audio and higher quality
presentation. There can be no assurance that the shift from ISA-based audio to
PCI-based audio will occur in a timeframe for the Company to benefit from its
PCI-based products and technologies. As new technologies are developed, there
can be no assurance that markets will develop for them, or that markets will
develop on a timely basis for the Company to benefit therefrom.

     The success of new products depends on a number of factors, including
timely completion of product development, market acceptance of the Company's and
its customer's new products and the Company's ability to offer new products at
competitive prices. Incorporating the Company's new products into its OEM
customers' new product designs requires the anticipation of market trends and
performance and functionality requirements of OEMs and the production of
products that can be available in a timely manner consistent with the OEMs'
development and production schedules. A failure in any of these areas could have
a material adverse effect on the Company's results of operations.

     Each successive generation of microprocessors has provided increased
performance, which could in the future result in a microprocessor capable of
performing advanced audio functions to an extent that the need or preference for
the Company's products could be diminished or eliminated. Conversely, each new
generation of technology, including digital audio technology, generally requires
increased processing power. In this regard, Intel Corporation has created the
MMX functionality with its Pentium line of processors and is promoting the
processing power of MMX for data and signal intensive functions such as graphics
and audio processing. The Company believes that advanced audio processing, done
in conjunction with either video or graphics processing is best performed with a
separate accelerator chip in addition to the host processor. There can be no
assurance that the increased capabilities of microprocessors in the future will
not adversely affect demand for the Company's products.

     Product Concentration and Expansion of Business Model

     Substantially all of the Company's revenues are related to advanced audio
solutions for the PC and consumer electronics markets and the Company expects
this to continue for the foreseeable future. The Company is just embarking on an
expansion of its semiconductor business model to provide for an increased number
of audio related products including audio cards and audio communications
combination cards. This expansion may require additional working capital funds
to provide for incremental inventory as well as broader marketing programs. The
failure of this market to continue to grow, any reduction in demand as a result
of increased competition in this market, technological change, failure by the
Company to introduce new versions of products acceptable to the marketplace or
other similar factors would have a material adverse effect on the Company's
results of operations.


                                       16
<PAGE>   17



     Competition and Pricing Pressures

     The markets in which the Company competes are intensely competitive and are
characterized by evolving industry standards resulting in relatively short
product life cycles, significant pricing and performance improvement pressures,
and frequent new product introductions. The Company expects competition to
increase in the future from existing competitors and from other companies that
may enter the markets with products that may be less costly or provide higher
performance or additional features. The Company is unable to predict the timing
and nature of any such competitive product offerings. In general, product prices
in the semiconductor industry have decreased over the life of a particular
product. The willingness of prospective customers to design the Company's
products into their products depends to a significant extent upon the ability of
the Company to price its products at levels that are cost-effective for such
customers. As the markets for the Company's products mature and competition
increases, the Company anticipates that prices for its products will generally
decline over time. If the Company is unable to reduce its costs sufficiently to
offset declines in product prices or is unable to introduce new, higher
performance products with higher product prices, the Company's results of
operations could be materially adversely affected.

     The Company anticipates that it will compete for the development of new
technologies and for the sale of semiconductor products with a number of
companies who have more extensive resources including financial, manufacturing,
technical, marketing and distribution. In addition, some of those firms may have
greater intellectual property rights, broader product lines and longer-standing
relationships with customers than the Company. The Company's competitors may
also include a number of emerging companies.

     Dependence on Credit Facility

     Because it has not been profitable to date, the Company has funded its
losses through a combination of equity and debt financing. In June 1998, the
Company entered into a Credit Facility with Goldman Sachs and Transamerica,
which provides for an aggregate maximum borrowing line of $40 million. The
interest rate on this Credit Facility is generally the prime rate plus 3% to 5%.
Accordingly, while the Credit Facility provides for working capital, the high
cost of servicing any borrowings thereunder could negatively effect the
Company's liquidity. The can be no assurance that the Credit Facility will
provide sufficient funding to meet the Company's future needs. In the event the
Company is required to secure additional capital, there can be no assurance that
such capital will be available on acceptable terms or at all. The Company's
inability to secure such potential future financing, if necessary, would have a
material adverse effect on the Company's business, financial condition and
results of operations.

     Factors Inhibiting Takeover

     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law, which imposes certain restrictions on the ability of a
third party to effect an unsolicited change in control of the Company. In
addition, the Company's Amended and Restated Certificate of Incorporation does
not provide for cumulative voting in the election of directors, and certain
provisions of the Company's Amended and Restated Certificate of Incorporation
and Bylaws, including the provision which divides the Board of Directors into
three separate classes, may have the effect of delaying or preventing changes in
control or management of the Company.

     Trading in the Non-NASDAQ Over-the-Counter Market; Disclosure Relating to
     Low Priced Stock

     The Company's Common Stock trades only on the OTC Bulletin Board and the
trading volume has been generally light. The Company does not currently meet the
requirements of the NASDAQ National Market or other national stock exchanges.
There can be no assurance that the Company will, in the future, meet such
listing requirements or that it will be accepted for trading on any such
national exchange.

     Because the Company's Common Stock trades on the Non-NASDAQ
Over-the-Counter market, an investor may find it more difficult to dispose of,
or to obtain accurate quotations as to the market value of, the Company's Common
Stock. In addition, because that Company's securities are not listed on NASDAQ,
trading in the Common Stock is also subject to certain rules promulgated under
the Securities Exchange Act of 1934, which require additional disclosure by
broker-dealers in connection with any trades involving a stock defined as a
penny stock (generally, a non-NASDAQ equity security that has a market price of
less than $5.00 per share, subject to certain exceptions). The additional
burdens imposed upon broker-dealers by such requirements may discourage
broker-dealers from effecting transactions in the Company's Common Stock, and
severely limit the market liquidity of the Company's Common Stock and the
ability of purchasers of the Company's Common Stock to resell such securities in
the secondary market.

     Risk of Additional Shares Sold in the Public Market

     Because the holders of the Series A Preferred and Series C Preferred shares
may convert such shares into shares of the Company's Common Stock at variable
conversion prices, the exact number of shares of Common Stock which the Company
may issue upon conversion of Series A Preferred and Series C Preferred shares is
not presently known, and may fluctuate based on the market value of the
Company's Common Stock. Because of the variable conversion price feature of the
Series A Preferred and Series C Preferred shares, holders of such shares may
have incentive to take certain actions, including shorting the Company's Common
Stock, to decrease the market price of such Common Stock. Upon a decrease in the
market price of the Company's Common Stock, holders of the Series A Preferred
and Series C Preferred shares may elect to convert such shares at the variable
conversion price and thereby receive a greater number of shares of the Company's
Common Stock. Short selling is illegal if used to manipulate the price of a
company's securities for profit, and the Company has no knowledge that any
holders of Series A Preferred or Series C Preferred shares intends to take any
action which may cause the price of the Company's Common Stock to fall. However,
there can be no assurance that holders of the Company's Series A Preferred or
Series C Preferred shares will not short the Company's Common Stock or take such
other actions, the effect of which may be to drive down the market price of the
Company's Common Stock.

     Concentration of Stock Ownership

     Currently, three parties control approximately 75% of the outstanding
Common Stock, each of who control at least 10% individually. There can be no
assurance that the liquidity of the market for the Common Stock will be
maintained at or increase over its current levels, and the trading price for the
Common Stock may be influenced by the volume and liquidity of the market for the
Common Stock. Sales of a large percentage of the Company's total outstanding
Common Stock may have an adverse effect on its market price.

     Dependence on Foundries

     The Company is a "fabless" semiconductor firm, which depends on outside
manufacturing resources for production of all of its semiconductor products.
Currently the Company utilizes two foundries, one domestic and one foreign for
production of its existing products. Both of these foundries have indicated to
the Company that they have the manufacturing availability to provide for the
Company's planned production of each of its products for the next twelve months;
however the Company's production relationship with each foundry is based only
upon purchase orders and there is no assurance that either foundry will continue
to provide adequate manufacturing capacity to the Company for its current level
of production or any potential increases in production levels. In the event
either or both foundries cease to manufacture the Company's semiconductor
products, the Company would have to contract with alternative foundries. There
can be no assurance that the Company would be able to contract with alternative
foundries in a timely manner or at all. The failure to do so would have a
material adverse effect on the Company's business, financial condition and
results of operations.

     The manufacture of semiconductor products is a highly complex and precise
process. Minute levels of contaminants in the manufacturing environment, defects
in the masks used to print circuits on silicon wafers, difficulties in the
fabrication process or other factors can cause a substantial percentage of
wafers to be rejected or a significant number of die on each wafer to be
non-functional. Many of these yield problems are difficult to diagnose, and
potentially time-consuming or expensive to remedy. There can be no assurance
that the Company's foundries will not experience irregularities or adverse yield
fluctuations in the manufacturing process of the Company's products in the
future, which could have a material adverse effect on the Company's business,
financial condition and results of operations.

     Dependence on Key Personnel

     The Company's success depends to a significant extent upon continued
services of key engineering, marketing, sales and management personnel. The
Company's employees may voluntarily terminate their employment with the Company
at any time. The Company recognizes the value of the contributions of each of
its employees and has developed compensation programs, including stock option
plans for the granting of options to all employees, designed to retain its
employees. Competition for such employees is intense and the loss of the
services of such employees could have a material adverse effect on the Company's
business, financial condition and results of operations.

                                       18
<PAGE>   19



     Dependence on Proprietary Technology

     The Company's ability to compete successfully will depend, in part, on its
ability to protect its proprietary technology. The Company relies on a
combination of patents, trade secret, copyright and trademark laws,
nondisclosure agreements and other contractual provisions and technical measures
to protect its proprietary rights. There can also be no assurance that such
measures will be adequate or safeguard the proprietary technology underlying the
Company's products, or that its agreements with employees, consultants and
others who participate in the development of its products will not be breached,
that the Company will have adequate remedies for any breach or that the
Company's proprietary information or trade secrets will not otherwise become
known. Moreover, notwithstanding the Company's efforts to protect its
intellectual property, there can be no assurance that competitors will not be
able to develop products which are equal or superior to the Company's products
without infringing any of the Company's intellectual property rights. In
addition, effective protection of intellectual property rights may be
unavailable or limited in certain countries. Accordingly, there can be no
assurance that the Company's means of protecting its intellectual property will
be adequate or that the Company's competitors will not independently develop
similar technologies or products.

     Although the Company does not believe that its products infringe the
proprietary rights of any third parties, there can be no assurance that
infringement or invalidity claims (or claims for indemnification resulting from
infringement claims) will not be asserted against the Company or that any such
assertions will not materially adversely affect the Company's business,
financial condition or results of operations. Irrespective of the validity or
the successful assertion of such claims, the Company could incur significant
cost with respect to the defense thereof which could have a material adverse
effect on the Company's business, financial condition or results of operations.

In February 1998, the Company was served with a suit for patent infringement
filed by Creative Technology Ltd., a Singapore corporation ("Creative"), and its
subsidiary, E-MU Systems, Inc., a California corporation ("E-MU") in the U.S.
District Court, Northern District of California. The suit alleges that the
Company's Vortex AU8820 Digital Audio Processor infringes on a patent that
describes a specific implementation for an electronic musical instrument
designed by E-MU. Creative and E-MU seek, among other things, a preliminary and
permanent injunction against continuing acts of infringement by the Company and
an accounting of damages plus interest. The Company believes that the action is
without merit and has commenced vigorous defense of this action.

     Shiva Holdings Limited ("Shiva") filed a cross-complaint against the
Company in December 1997 in the Superior Court of Santa Clara, California. The
cross-complaint alleges breach of contract; breach of implied covenant of good
faith and fair dealing, fraud and negligent misrepresentation in connection with
the Agreement for Purchase of Certain Assets entered into between Shiva and the
Company in February 1996. The Company had filed an action against Shiva for
breach of contract and specific performance in connection with the failure of
Shiva to perform under the February 1996 agreement between the companies. All
claims in these actions were settled in July 1998 with the termination of the
agreement without monetary exchange between the parties.

     Litigation may be necessary to resolve the claims asserted by Creative,
E-MU and any other claims asserted in the future to defend against claims of
infringement or invalidity or to enforce and protect the Company's intellectual
property rights. There can be no assurance that the Company will prevail in any
such litigation, and any such litigation, whether or not determined in the
Company's favor or settled by the Company, would be costly and would divert the
efforts and attention of the Company's management and technical personnel from
normal business operations, which could have a material adverse effect on the
Company's business, financial condition and results of operations. Adverse
determinations in litigation could result in the loss of the Company's
proprietary rights, subject the Company to significant liabilities, require the
Company to seek licenses from third parties or prevent the Company from
licensing its technology, any of which could have a material adverse effect on
the Company's business, financial condition and results of operations.

     Year 2000 Compliance

     The Company uses a number of computer software programs and operating
systems in its internal operations, including applications used in financial
systems and various administrative functions. To the extent that these software
applications contain source code that is unable to appropriately interpret the
upcoming calendar year 2000, some level of modification or even possibly
replacement of such applications could be necessary. Given the information known
at this time about the Company's systems, it is currently not anticipated that
such "Year 2000" costs will have a material impact on the Company. The Company
is not aware that any of its key suppliers or customers are not fully "Year
2000" compliant. If any of its key suppliers or customers are not yet fully
"Year 2000" compliant, there can be no assurance that such non-compliance would
not have a material adverse effect on the Company's business, financial
condition or results of operations.

ITEM 6. EXHIBITS AND REPORTS ON FORM 8-K

     (a) Exhibit index at page 23.

     (b) Reports on Form 8-K:

         On June 15, 1998, the Company filed a Form 8-K with the Securities and
         Exchange Commission ("SEC") disclosing the completion of three
         financing transactions. These included (1) the sale of $5 million of
         Aureal Series C Preferred Stock, (2) the conversion and termination of
         the Company's previous line of credit in exchange for 39,375 shares of
         Aureal Series B Preferred Stock, and (3) the establishment of a new $40
         million Revolving Credit Facility with Goldman Sachs and Transamerica.

         In conjunction with the SEC's review of a Form S-2 filed to register
         shares of Aureal Common Stock, the SEC requested that certain
         amendments be made to wording in the above Form 8-K. An amended Form
         8-K/A was filed in response to such request on July 2, 1998.

         On March 16, 1998, the Company filed a Form 8-K disclosing the sale of
         $5 million of Aureal Series A Preferred Stock. This Form 8-K was
         amended via filing of Form 8-K/A's on June 3, 1998 and July 2, 1998,
         again in response to SEC comments related to the review of the above
         referenced Form S-2.
