<font face="Courier New">Dear All,<br>
<br>
I noticed there is no spectrogram function in Scilab that provides
both graphic and numerical </font><font face="Courier New">output.
There is a function mapsound(), which plots a spectrogram without
numerical information and without control over important aspects
such has FFT length or windowing function. By the way, in the
field of digital sound processing the usual name for this is
spectrogram, not mapsound, which is a bit confusing.<br>
<br>
I created a spectrogram() function. Even if it doesn't yet comply
with the recommended style for Scilab functions (particularly
regarding error handling or manual page), I think it might be
useful for some users. I attach the function and a test script.<br>
<br>
