GPU used for audio DSP

another /. post, a group proposing to steal the video card processor
for audio use :

perhaps it's a pipe dream, but this could have a significant impact if
it caught on. problem is, i usually get the cheapest 8M vid card i
can (although this is getting harder, the cheapest card i can find
these days is a $40 32M AGP . . .)

cheers,

I would say that a processor more dedicated to audio would be a better
choice. There are such things as macs and fpgas.

I don't think this is intended as a serious pro tool, but rather
something that game manufacturers can take advantage of, getting some
extra DSP for free in computers that have the card which can do this
trick.

By the way, what does GPU stand for? Graphics Processing Unit? It
wasn't defined anywhere in the referenced article. I guess to some
people it's as common as CPU or A/D but real people read those
articles, too.

Graphics Processing Unit: Like the CPU (central processing unit), it
is a single-chip processor. However, the GPU is used primarily for
computing 3D functions. This includes things such as lighting effects,
object transformations, and 3D motion. These types of calculations are
rather straining on the CPU, but since the specialized GPU can take
care of most of the 3D calculations, it helps the computer run more
effienciently, and, of course, faster.

well, a dedicated DSP chip that can do a mX + Y process will always be
the best, and i know GPU (you got it right) are optimized for
different operations, but if i had to wait 15% for a filter because
some of the processing was dumped over to the GPU, it'd be a cool
perk.

personally, i think all the tweaking and what not that would have to
be done would undermine any gains. seems like it would work for
plugins that supported it, and would undermine our already unstable
systems. . .
