Use DSP features of sound card

Started by fakufaku July 23, 2008
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. K.

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. Regards, John
