[comp.sys.next] DSP Programming

Hello everyone.   I 'm beginning to work on my MSEE research project.
The project will be basically a product that fits between Digital ears and
A/D64x.  The hardware is not the problem.  A lot of the research I will be
doing will be related to the DSP.  I plan to use the DSP offline to do
multiple effects, such as, reverb, delay, gate, etc.  I don't think the DSP
is fast enough to do realtime recording to harddisk and effects processing
simultaneously.  I could be wrong.  So anyone out there who knows where I
can get some information on digital effects proccessing let me know.  Once
I write the software for editing the data it will be public domain with
souces.  The hardware I'm designing will more than likely be patented and
for sale either as a do-it-yourself kit or low cost fully assembled
product.

INMHO the prices that everyone wants for their A/D hardware to hang on the
DSP port are way to high.  A/D converters that do 2x oversampling are only
$25 add some other hardware, case, and I get about $150 in parts.  This is
no whre near the $600 minimum that the hardware is selling for.

Also send me information on what you might like to see in the software
for effect and what hardware features you might like.  I plan to include,
if I can ever get any information, an AES/EBU input and output for DAT
compatibility.  My product will have at least 2x oversampling at 48 and
44.1k with sampling rate adjusments down to about 8k.

                  Thanks, Kent
