There are programs that do this on the internet. Look at
the really nice book "Linux Multimedia Guide" by Jeff
Traner. It is featured on: http://www.ora.com/info/linux/
There are also DPS boards that run on the PC, that have DACs
and ADCs. Many of these chips come with C compilers and FFT
code included, such as the AT&T chip and the TI TMS chips.

Many others know mcuh more than I do about this topic,
I have already told you more than I know, so dont ask me
more.
