We're developing a voice annotation application and would like to
stick with just one of the many compression algorithms.  What's *your*
favorite and why?  (I'll compose an article based upon your responses.)

Goal: We'll be sampling at 8kHz and need to reduce the data to 4 bits
per sample.

Possibilities: The "contestants" appear to be "scaled MULAW" and ADPCM.

"Scaled MULAW" is typified by the Artisoft "Sounding Board" hardware
and software.  They start with 13-bit PCM, compand to 8-bit MULAW
(which has the advantage of being in the public domain), then compress
approximately 2:1 again by converting every 32 samples to 4 bits each
plus a "scaling" byte.  (A proprietary but simple algorithm.)

"ADPCM" is typified by Sound Blaster (Creative Labs) and others that
start with either 8- or 12-bit samples then reduce to 4-bit samples
using ADPCM.  The primary disadvantage of this technique (it seems to
us) is the lack of standards for ADPCM.
 
Given that background, which technique would *you* use?  Do you have an
opinion as to which "sounds better", Scaled MULAW or ADPCM?  What are
your personal experiences either as a user or developer/engineer?
 
Thanks!      ...doug

Hi, netters,

I will be very grateful if someone can tell me where to buy a VGA compatible
projection TV.  That is, LCTV inside and a digital RGB input projector.  All
I know in the market is 320*220 projector with RGB digital input.  

Please reply to y1@wilbur.psu.edu,  Tel.# or name and address of the company
or dealers.  

Thanks in advance.

Could someone send me a copy of the list of magazines that deal

OR

I wanted to get the CD-ROM version, but Firmware Design (the Australian

get the CD through an "Apple distributor", rather than from them. So I said
to hell with it and asked him to order the floppy-only version.

Anybody else in the Australasian region been given a similar runaround?

	The beam projectors are also beginning to be a bit long of tooth (see

issue of portability is important to us, as beams seem to be the only things
which can handle some of the material we intend to project, specifically,
full motion video, and the output of workstations.
	We are interested in *one gun machines* because of the portability.
However, we will hear arguments that 3 gun machines can be used, and still
be in focus after being trundled down a hallway over bumpy tile floors, or
the like, if you care to make them.  We're just darned open minded kindsa

I am having a problem that is driving me crazy!

I have set up a program that will access very specific locations in a
Microsoft Waveform from ToolBook.  I did this in ToolBook 1.5 with Windows
3.0.  Everything was working just fine.

I just transferred my program to a system with ToolBook 1.53 and Windows 3.1
and many of the sounds are being cut off!  Why is this happening?  What
can I do about it?!

It does not seem to be ToolBook, since I get the same error when I directly
access the Waveform from WaveEdit.

Please email me if you have any help or suggestions!
Thanks!

Date: 1 Sep 92 19:44:33 GMT
Article-I.D.: alice.23607
Organization: AT&T Bell Laboratories, Murray Hill NJ

I'm look for source code (C preferred) that allows a DOS
program to send bytes to a parallel port in some fashion
that lets the DOS program continue computations.  For
instance, imagine a signal processing program that produces
8-bit audio samples in (barely) real-time and a digital/audio
converter sitting on the parallel port.  The program produces
a small buffer of samples every few milliseconds.  The DAC
will probably be playing 8KHz MULAW, but that doesn't
really matter.  Print spoolers might also have such functions.

It seems that everything in the PC world wants to open a file
and play a file, usually while nothing else is happening.
I need routines that allow the program to queue up each new
buffer and get on with computing the next one.  With a fast PC,
my guess is that I could live with an interrupt per byte if
need be.

The last item on the wish-list is that someone has such
routines for a 32-bit environment.  I'm using Watcom C9.0
and the DOS/4GW extender.

Any pointers would be greatly appreciated.  Please respond via
e-mail.  I'll post a collection of interesting responses if
warranted.

the voyager video stack to go with this but I am considering some of my own

is a BIG step for me as I have done a SMALL amount of scripting in the past,
but
nothing of this caliber.  Any hints or sample scripts are appreciated.  We own
a lot of software but seem to have misplaced the documentation (I think the guy

Any hints, suggestions are appreciated !!!

Ideally you can use Creative Labs utilities to do this for you with a SoundBlaster. I would check into whatever the sound card came with first
since you will be using it for the sound...They all seem to support this type of thing...Another way would be a presentation in one of many of the Multimedia packages like Macromind Action!, Macromedia Director or a combination of Autodesk screens with a script to do the sound.

I found the multimedia software I was looking for from a colleague, if
anybody is interested.It is very useful. It is for SUN and performs the
compression in JPEG. It has file conversion facilities in GIF, PPM,PGM,
TIFF, SUN raster, XBM, XWD, FAX G3 formats. It has also an option to
change from these formats to PS format and you can later print it.
It also mails the compressed image by email. At the other end the receiver
can make necessary format changes and view the image. My colleague says
he is very happy with this product, and it is indeed very useful.

Hi!

I seriously considering getting into QuickTime movie making, but I still
have a couple of questions that I hope some of you multimedia freaks can
help me with:

1. How many frames pr. second will the Videospigot LC card record on a Mac
   LC II ("normal" window size, compression rate = ?)? What about the
   IIsi card for the IIsi?

2. Is the MediaTime card from Raster-Ops a NuBus card? Will this card fit
   into the Mac IIsi? If yes, how many frames pr. second will it record,
   and how good is the quality?

3. How many movie-clips can you use for putting together QuickTime movies
   in Adobe Premiere? What about DiVA Videoshop?

4. How long (in seconds and MB) can these movie-clips be (is it a question 
   of harddisk space, or RAM)?

5. When is the new version of Adobe Premiere (2.0) released?

6. Which should I choose; Adobe Premiere or DiVA Videoshop?

7. How large should the harddisk be, and how much RAM ought I have?

I would also appreciate some feedback from QuickTime moviemakers, what
they're experiences are (the good, the bad and the darn right ugly) and
so on.
