Sensible.  The audio processor is in the lead so far.

I'm afraid I'm not familiar with Extrema Processing.  Can you give me 
some pointers?  Do you knoe if it's used in speech recognition?

Using Mel-Frequency Cepstral Coefficients removes many speaker-dependent 
properties of the signal (like voice pitch).  I don't know much about 
voice identification, but I imagine you'd abstract out a different set 
of features (e.g., you'd probably want to keep voice pitch).

Best wishes

Ivan
