   I am having trouble locating source code for raw waveform analysis.
The algorithms are needed for research in the 'speech recognition'
area.

             The algorithms/techniques I intend to look at are :-

                    (a)  FFT and the Inverse FFT
                    (b)  Cepstral Analysis
                    (c)  LPC (linear predictive coding)

   If anyone can help with source code for any of the above, or can
provide an FTP site address where information can be obtained, this
would be greatly appreciated. The preferred language would be 'C' but
psuedo-code or any other language would also be useful.


                Thanks in advance,
