02 Nov 2004	Eric Bultemeier	Did not perform as expected. Recommend not using out of the box. Note: output B of specgram is not conjugate symmetric.
05 Nov 2004	Jesper mortensen	It really works for audio processing! Try to process a wave file through specgram then modify it a little bit, let´s say change the high frequency content amplitude and return it into time domain. You´ll hear the difference.
05 Nov 2004	Arn Lyk	I used it for wave field synthesis and it works!
21 May 2008	Someguy there	Might not work as-is with MATLAB® 7.6, R2008a . Get warnings and errors.
