(2)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation
The interim consolidated financial statements of the Company are condensed and
do not include some of the information necessary to obtain a complete
understanding of the financial data. Management believes that all adjustments
necessary for a fair presentation of results have been included in the unaudited
consolidated Financial Statements for the interim periods presented.
Accordingly, your attention is directed to footnote disclosures found in the
December 31, 1997 Annual Report and particularly to Note 1 which includes a
summary of significant accounting policies.

Basis of Consolidation
The consolidated financial statements include the accounts of Spatializer Audio
Laboratories, Inc. and its wholly owned subsidiaries, Desper Products, Inc. and
MultiDisc Technologies, Inc. All significant intercompany balances and
transactions have been eliminated in consolidation.

Revenue Recognition
The Company accrues foundry revenues based on licensee royalty reports,
management estimates and reports from third parties. At March 31, 1998, the
Company accrued $362,750 of royalty revenue from a major customer based on the
results of a royalty audit, which was settled in June 1998 for $350,000.

Research and Development Expenditures
The Company expenses research and development expenditures as incurred.

(3)      LOSS PER SHARE

Loss per share for the three and nine months ended September 30, 1998 includes
the effect of approximately $262,000 of the beneficial conversion feature of the
Series "A", 7% Convertible Preferred Stock as well as dividends in arrears of
$96,250 related to the Series "A", 7% Convertible Preferred Stock.

The following table presents options and warrants to purchase shares of common
stock that were outstanding during the nine month periods ended September 30,
1998 and 1997 which were not included in the computation of diluted loss per
share because the impact would have been antidilutive:

(4)      COMPREHENSIVE INCOME

The Financial Accounting Standards Board issued Statement No. 130, Reporting
Comprehensive Income ("SFAS 130"), in June 1997. SFAS 130 establishes standards
for reporting and display of comprehensive income and its components in
financial statements. SFAS No. 130 is effective for fiscal years beginning after
December 15, 1997. The Company adopted SFAS No. 130 on January 1, 1998.
Comprehensive income (loss) is the change in equity of a business enterprise
during a period from transactions and all other events and circumstances from
non-owner sources. Other comprehensive income (loss) includes foreign currency
items, minimum pension liability adjustments, and unrealized gains and losses on
certain investments in debt and equity securities. The Company did not have
components of other comprehensive income (loss) during the three-month and nine
month periods ended September 30, 1998 and 1997. As a result, comprehensive loss
is the same as the net loss for the three-month and nine-month periods ended
September 30, 1998 and 1997.

(5)      SEGMENT REPORTING

The following table presents information about reported segment losses and
segment assets as of and for the nine-month periods ended September 30, 1998 and

(7)       CONTINGENCIES

Legal

         On September 18, 1998, the U.S. Court of Appeals upheld U.S. District
Court Judge William D. Keller's decision of August 29, 1996 in which the
District Court had granted the Company's summary judgment motion in its entirety
and denied the motion by QSound in the patent infringement litigation between
the Company and QSound. The decision affirmed the District Court's ruling in all
aspects and confirmed that Spatializer is entitled to distribute its products
free of any infringement claim by QSound. The Company intends to maintain and
continue to pursue its counterclaims for damages and for a decision that the
QSound patent is invalid.

         In the District Court decision, which was upheld by the Court of
Appeals, the District Court had found that the Company's IC (Integrated Circuit)
does not infringe the QSound patent and had denied in QSound's motion with
respect to infringement. The Company's claim that the QSound patent is invalid
was not decided in the summary judgment and, since the issues which the District
Court would have been required to consider on the patent invalidity claim are
similar to certain issues considered in the infringement claim, QSound was
granted the right to immediately appeal the denial of its motion and trial on
the invalidity issue was deferred until after that appeal. In substance, the
Court of Appeals decision further confirms the Company's position that there is
no infringement by the Company's IC of any patent held by QSound and that the
claims by QSound were without merit.

(8)       SALE OF PREFERRED STOCK

         On April 14, 1998, the Company entered into a private placement for up
to $5 million of which $3 million was funded at September 30, 1998. In
connection with the private placement, the Company authorized 100,000 shares of
a new Series A, 7% Convertible Preferred Stock at a stated price of $50 per
share and issued 60,000 shares for $3 million. In connection with the April
funding, the Company issued purchase warrants, exercisable for three years and
entitling the holders to acquire one share of the Company's common stock for
each warrant. Of the warrants, 450,000 were issued and 150,000 warrants were
issued to placement agents. The investor warrants are exercisable at 140% and
the placement warrants are exercisable at 120%, respectively, of the average
closing bid price of the Company's common stock for the 10 days preceding the
closing. In addition, cash placement fees of 10% were paid. A related party of
the Company received 50,000 of the placement agent warrants and $100,000 of the
placement agent cash fee for arranging $1 million of the $3 million investment.
As of September 30, 1998, $1 million of the remaining $2 million of the funding
was due but had not yet been received.

         Holders of the Series A Preferred Stock have a right to convert their
shares, at their option on the earlier of (x) ninety (90) days after issuance or
(y) on the effective date of a Form S-3 Registration Statement (the "Conversion
Date") with such conversion to be based on a per share conversion price
("Conversion Price") equal to the lesser of a price that reflects a discount
(the "Conversion Discount") to the average of any three (3) consecutive closing
bid prices for the Company's Common Stock within twenty (20) trading days
immediately prior to the conversion date (the "Floating Conversion Price") or a
price which is equal to one hundred thirty percent (130%) of the closing bid
prices of the Company's Common Stock for the ten (10) trading days immediately
preceding the date of issuance (the "Fixed Conversion Price") provided that in
determining the Conversion Price, the holder shall not count any day on which
its sales account for greater than twenty percent (20%) of the volume of the
Company's Common Stock and on which the holder has sales in the last hour of
trading. The Conversion Discount shall be equal to fifteen percent (15%) if the
Conversion Rights are exercised within one hundred twenty (120) days of first
issuance of the Series A Preferred Stock and shall be equal to seventeen and
one-half percent (17.5%) if the Conversion Rights are exercised after one
hundred (120) days and prior to one hundred forty-nine (149) days of first
issuance of the Series A Preferred Stock. The applicable Conversion Discount
increases by five percent (5%) if the Company is de-listed on NASDAQ. In
addition, the percentage of shares that can be converted at any one time is
limited during such time periods and the holders cannot own more than 4.99% of
the equity of the Company after the Conversion.

         The beneficial conversion feature of the Series A Preferred Stock will
be recorded as a dividend using the most favorable conversion terms available to
the shareholder to calculate the dividend in accordance with FASB (Emerging
Issues Task Force) Topic D-60. Since the Company has an accumulated deficit and,
under Delaware Law, must charge dividends against additional paid in capital,
the net impact of recording the beneficial conversion feature is zero since both
sides of the entry are recorded in additional paid in capital. At September 30,
1998, dividends in arrears were $96,250.

         In the private placement, the participants were granted certain rights
to participate in the separate financing of approximately $6 million currently
being pursued by the Company to fund the commercial introduction of its
MultiDisc CD/DVD server technology. However, as reported by the Company on
September 25, 1998, the Company has decided to refocus on the core audio
technologies and to properly position the MultiDisc assets for sale. Therefore
this financing is not currently being pursued actively.

Item 2. Management's discussion and analysis of financial condition and results
of operations

  RESULTS OF OPERATIONS

This form 10-Q contains forward-looking statements, within the meaning of the
Private Securities Reform Act of 1995, which are subject to a variety of risks
and uncertainties. The Company's actual results, performance, or achievements
may differ significantly from the results, performance, or achievements
expressed or implied in such forward-looking statements.

  REVENUES

         Revenue decreased to $390,000 in the three months ended September 30,
1998 from $833,000 in the comparable period last year, a decrease of 53%.
Revenue in the nine-months ended September 30, 1998 decreased to $1,588,000 from
$1,928,000 in the comparable period last year, a decrease of 18%. Revenues
include licensing and royalties pertaining to the licensing of Spatializer(R)
audio signal processing designs, product development and evaluation fees at
MultiDisc Technologies, Inc. and sales of professional recording systems and
consumer products. The decrease in revenue results primarily from decreases in
recurring royalties for the licensing of the Spatializer technologies and on
chip foundry sales incorporating the usage of Spatializer(R) advanced audio
solutions by the Company's licensees, reflecting weakness in the Asian Market,
as well as the signing, in the third quarter of 1997, of a multi-year,
multi-technology license agreement for which there was no comparable license
agreement in the current quarter.

         Desper Products, Inc.'s licensing and royalty revenues decreased to
$390,000 and $1,538,000 in the three and nine months ended September 30, 1998,
from $833,000 and $1,928,000 in the comparable periods last year, decreases of
53% and 20%, respectively.

         In addition, there were negligible product sales in the three and nine
months ended September 30, 1998 as compared with the same periods in 1997. The
Company made the decision in late 1997 to discontinue sales of hardware products
in order to focus its efforts on licensing and software-only products. Product
sales for the three months ended September 30, 1998 were ($1,000) as compared to
$27,000 for the comparable period last year. Product sales for the nine months
ended September 30, 1998 were $17,000 as compared to $313,000 for the comparable
period last year.

  GROSS PROFIT

         Gross profit decreased to $385,000 (99% of revenue) in the three months
ended September 30, 1998 from $797,000 (96% of revenue) in the comparable period
last year, a decrease of 52%. Gross profit for the nine-months ended September
30, 1998 decreased to $1,553,000 (98% of revenue) from $1,705,000 (88% of
revenue) in the comparable period last year, a decrease of 9%. Gross profit
decreased due to the decrease in revenue. Gross margin increased due to the
shift in product mix to licensing revenues, which provide a higher margin than
product revenues.

  OPERATING EXPENSES

         Operating expenses increased to $1,480,000 (379% of revenue) in the
three months ended September 30, 1998 from $1,445,000 (173% of revenue) in the
comparable period last year, an increase of 2%. Operating expenses in the
nine-months ended September 30, 1998 increased to $4,624,000 (291% of revenue)
from $4,552,000 (236% of revenue) in the comparable period last year, an
increase of 2%. The increase in operating expenses for the three months ended
September 30, 1998 results primarily from increased general and administrative
and sales and marketing expenses partially offset by lower research and
development expenses. The increase in operating expenses as a percentage of
sales in the three and nine months ended September 30, 1998 result from the
decline in revenue.

General and Administrative

         General and administrative expenses increased to $655,000 (168% of
revenue) in the three months ended September 30, 1998 from $458,000 (55% of
revenue) in the comparable period last year, an increase of 43%. General and
administrative expenses increased to $1,822,000 (115% of revenue) in the
nine-months ended September 30, 1998 from $1,567,000 (81% of revenue) in the
comparable period last year, an increase of 16%. The increase in general and
administrative expense result from staffing of key executive positions and
related expenses in 1998 that were vacant in the prior comparable period.

Research and Development

         Research and Development expenses decreased to $610,000 (156% of
revenue) in the three months ended September 30, 1998 from $775,000 (93% of
revenue) in the comparable period last year, a decrease of 21%. Research and
Development expenses decreased to $1,774,000 (112% of revenue) in the
nine-months ended September 30, 1998 from $2,154,000 (112% of revenue) in the
comparable period last year, a decrease of 18%. The decrease in research and
development in the three and nine month periods result from lower research and
development expenditures for prototypes of the MultiDisc eXpandable Network
Server and XNS technology required in the current period compared to the prior
year as well as efficiencies in research and development activities at Desper
Products Inc.


Sales and Marketing

         Sales and marketing expenses increased to $215,000 (55% of revenue) in
the three months ended September 30, 1998 from $212,000 (25% of revenue) in the
comparable period last year, an increase of 1%. Sales and marketing expenses
increased to $1,028,000 (65% of revenue) in the nine-months ended September 30,
1998 from $831,000 (43% of revenue) in the comparable period last year, an
increase of 24%. The increase is attributed to the hiring of additional sales
executives at Desper Products Inc., and the initiation of marketing activity at
MultiDisc Technologies, Inc. as it enters its next phase of development.

NET LOSS

         Net loss increased to $1,124,000 (288% of revenues) in the three months
ended September 30, 1998 from $661,000 (79% of revenues) in the comparable
period last year, an increase of 70%. Net loss increased to $3,137,000 (198% of
revenue) in the nine-months ended September 30, 1998 from $2,859,000 (148% of
revenue) in the comparable period last year, an increase of 10%. The increased
net loss for the three and nine month period is primarily a result of the
decrease in revenue and gross profit. The increase in loss per share resulted
from the beneficial conversion discount on the issuance of the Preferred Stock.

LIQUIDITY AND CAPITAL RESOURCES

         At September 30, 1998, the Company had $258,000 in cash and cash
equivalents as compared to $577,000 at December 31, 1997. The decrease in cash
and cash equivalents is attributed to: (i) cash used for research and
development at MDT on the Modular Scalable Storage Library, (ii) the repayment
of $400,000 of borrowings on a bank line of credit and (iii) cash used in other
operating activities. This was partially offset by net proceeds of $2,620,893
from the sale of preferred stock on April 14, 1998 and proceeds from a $650,000
related party note payable. The Company had negative working capital of $217,000
at September 30, 1998 as compared with working capital of $283,000 at December
31, 1997. The Company's future cash flows are expected to come primarily from
audio signal processing licensing, Foundry and Original Equipment Manufacturers'
("OEM") royalties, common and/or preferred stock issuances including warrant and
option exercises, through venture and/or strategic investors or product
development revenues of MDT. At September 30, 1998 the Company had six Foundry
licensees, seventy-two OEM Licensees and eight authorized customers for its
audio signal processing business as compared with five Foundry licensees and
sixty-two OEM Licensees and fourteen authorized customers at December 31, 1997.
The Company is actively engaged in negotiations for additional audio signal
processing licensing arrangements and equity capital, which should generate
additional cash flow without imposing any substantial costs on the Company.

         The Company continues to have no material long-term obligations and has
no present commitments or agreements that would require any long-term debt or
obligations to be incurred. The Company owed $762,500 to related parties as of
September 30, 1998 and $112,500 at December 31, 1997.

         On April 14, 1998, the Company entered into a private placement for up
to $5 million of which $3 million was funded at September 30, 1998. In
connection with the private placement, the Company authorized 100,000 shares of
a new Series A, 7% Convertible Preferred Stock at a stated price of $50 per
share and issued 60,000 shares for $3 million. In connection with the April
funding, the Company issued purchase warrants, exercisable for three years and
entitling the holders to acquire one share of the Company's common stock for
each warrant. Of the warrants, 450,000 were issued and 150,000 warrants were
issued to placement agents. The investor warrants are exercisable at 140% and
the placement warrants are exercisable at 120%, respectively, of the average
closing bid price of the Company's common stock for the 10 days preceding the
closing. In addition, cash placement fees of 10% were paid. A related party of
the Company received 50,000 of the placement agent warrants and $100,000 of the
placement agent cash

fee for arranging $1 million of the $3 million investment. As of September 30,
1998, $1 million of the remaining $2 million of the funding was due but had not
yet been received.

         Holders of the Series A Preferred Stock have a right to convert their
shares, at their option on the earlier of (x) ninety (90) days after issuance or
(y) on the effective date of this Registration (the "Conversion Date") with such
conversion to be based on a per share conversion price ("Conversion Price")
equal to the lesser of a price that reflects a discount (the "Conversion
Discount") to the average of any three (3) consecutive closing bid prices for
the Company's Common Stock within twenty (20) trading days immediately prior to
the conversion date (the "Floating Conversion Price") or a price which is equal
to one hundred thirty percent (130%) of the closing bid prices of the Company's
Common Stock for the ten (10) trading days immediately preceding the date of
issuance (the "Fixed Conversion Price") provided that in determining the
Conversion Price, the holder shall not count any day on which its sales account
for greater than twenty percent (20%) of the volume of the Company's Common
Stock and on which the holder has sales in the last hour of trading. The
Conversion Discount shall be equal to fifteen percent (15%) if the Conversion
Rights are exercised within one hundred twenty (120) days of first issuance of
the Series A Preferred Stock, shall be equal to seventeen and one-half percent
(17.5%) if the Conversion Rights are exercised after one hundred (120) days and
prior to one hundred forty-nine (149) days of first issuance of the Series A
Preferred Stock. The applicable Conversion Discount increases by five percent
(5%) if the Company is de-listed on NASDAQ. In addition, the percentage of
shares that can be converted at any one time is limited during such time periods
and the holders cannot own more than 4.99% of the equity of the Company after
the Conversion.

         The beneficial conversion feature of the Series A Preferred Stock will
be recorded as a dividend using the most favorable conversion terms available to
the shareholder to calculate the dividend in accordance with EITF Topic D-60.
Since the Company has an accumulated deficit and, under Delaware Law, must
charge dividends against additional paid in capital, the net impact of recording
the beneficial conversion feature is zero since both sides of the entry are
recorded in additional paid in capital. At September 30, 1998, dividends in
arrears were $96,250.

         In the private placement, the participants were granted certain rights
to participate in the separate financing of approximately $6 million currently
being pursued by the Company to fund the commercial introduction of its
MultiDisc CD/DVD server technology. However, as reported by the Company on 
September 25, 1998, the Company has decided to refocus on the core audio 
technologies and to properly position the MultiDisc assets for sale. Therefore 
the financing is not currently being pursued actively.

         On September 25, 1998, the Company announced that its Board of
Directors was refocusing the Company's business on the exploitation of its audio
technologies, and, as noted above, to properly position the MultiDisc assets for
sale. In reaching this decision, the Board of Directors noted that the September
18, 1998 decision by the U.S. Court of Appeals confirming the District Court's
grant of a Summary Judgment in favor of the Company and against Qsound was
expected to eliminate the negative market perceptions faced by the Company over
the last four years. Currently the Company is actively pursuing licensing
opportunities, including possible strategic alliances and capital funding
opportunities based on its core audio technologies. In reaching its decision of
September 25, 1998, the Company indicated that while it recognized the prospects
of MultiDisc, the capital investments required to properly commercialize the
technology was beyond its current capacity and, therefore, it had made the
decision to seek a sale transaction. Effective as of that date, Steven D.
Gershick resigned as chief executive officer of the Company and as president of
MultiDisc Technologies, Inc., but continues to serve as chairman of the board of
the Company. Henry R. Mandell, who joined the Company in March, 1998 as senior
vice president finance was designated as interim chief executive officer to
oversee all of the corporate activities with support from Kibel Green Issa, Inc.
Michael Bolcerek resigned as president of Desper Products, Inc.

         Funds generated from the financing business activities and capital
transactions described above, as well as cash generated from the Company's
existing operations and the cost reductions being undertaken, are expected to be
sufficient for the Company to meet its operation obligations during the next
twelve months. However, if the refocus on the audio technologies strategy is not
successful, if a strategic alliance including capital funding is not concluded,
or if an appropriate transaction is not undertaken with respect to the MultiDisc
activities, the ability of the Company to meet its operating needs will be
materially adversely affected. As of September 30, 1998, the Company had a
negative working capital of $217,000 and, absent continued and improved revenues
and successful funding activities, the Company may not be in a position to
resolve this deficit.

         The Company has responded to inquiries from NASDAQ and attended a
hearing with respect to its continued listing on October 29, 1998 at which time
it outlined its strategy for continued listing. A decision is pending.

YEAR 2000

The Company is aware that many computer software programs may not currently be
designed to properly handle the system date change after December 31, 1999. The
Company is addressing this contingency with its computer consultants and is
currently upgrading its software programs, the cost of which is expected to be
no more than $15,000.

                           PART II. OTHER INFORMATION


ITEM 1.        LEGAL PROCEEDINGS

On September 18, 1998 the U.S. Court of Appeals for the Federal Circuit issued
its decision (97-1135) affirming the decision of the U.S. District Court for the
Central District of California (No. CV 94-7276) in which the District Court had
granted the Company's Motion for Summary Judgment in its entirety and had denied
the Motion by QSound Labs, Inc. ("QSound") in the patent infringement litigation
which had been pending between the Company and QSound since 1994. The Court of
Appeals decision affirmed the District Court's ruling in all respects, with the
effect that it confirmed that the Company is entitled to distribute its products
free of any infringement claim by QSound. The Company intends to maintain and
continue to pursue its counterclaims for damages and for a determination that
the QSound patent is invalid.
