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. Jont Allen
