Hi!

 I'm in the process of writing a master thesis on Speech Recognition,
and the NeXT seems ideal for this purpose. We've just acquired a NeXT, 
and are trying it's capabilities. It's essential for this project,
that spectrum analysis can be done effectively, so that recognition
can be done in real time. On the NeXT I've found some assembler files
for doing FFT (We are really interested in getting the Cepstrum Coefficients)
on the DSP chip. We are, however, not asm. experts. Are there anyone
out there who have done any work on this? We would like a piece of code,
which will take a CODEC snd-file, down-load it to the DSP chip, perform
FFT analysis, and make the output available for further analysis.

	Thanks,
