One could think about using 3D graphics hardware
for audio DSP
purposes. There are commercial projects which do that (only for
Windows AFAIK).
There are also some free projects, but IIUC, the kinds of precessing
you can do are quite limited, it has to be fairly high latency as
you need to move the audio data to the card in large blocks.
