I am interested in using the audio input of a Sun SparcStation 1+ to do
some voice recognition work. In this connection it would be useful to
have a frequency analysis of the recorded signal. Has anyone written code
which will transform the recorded audio signal into a (time-dependent)
frequency distribution? Ideally, the program would display an image which
has time on one axis, frequency on the other and the darkness of the image
at a point depends on the intensity of the specified frequency at the
specified time (plots like this are produced by some hardware frequency
analyzers). I am not looking for real-time conversion, something which
would read the stored audio data from a period of recording would be
great.
