If you are only dealing with audio signals, there are certainly a number of
possibilities.  There are a large number of 32-bit high performance
microcontrollers on the market that would be able to accomplish even the
most complicated DSP tasks (at audio frequencies). My personal favorite is
the Hitachi SH3 and beyond.... I would think that a lot of 16-bit micros
would be fast enough to do any real-time filtering of audio signals.  But
if you want to do more complicated things, your best bet is to stick with
the DSPs.  The 56303 eval kit from Motorola has an audio CODEC on it, which
makes it neat for experimenting..
