Use DSP features of sound card

Hi, I was wondering if it is possible to access and use the dsp features of
sound cards in order to get some hardware acceleration for computationaly
intensive algorithms like fft or filtering.
I was also thinking of graphic cards.
Did anyone try this before ?

Thanks a lot.

I was not aware that sound cards had such built-in operations such as
FFTs. Maybe some of the more expensive cards do but you need an API
of some sort. The basic windows one would not be enough I expect.

The graphics chip company Nvidia gives a lot of support for 
those wanting to use the parallel-processing capabilities of 
its products.  See their website for details.
