Thanks Antoine, the stacksize('max'); command allowed me to run mapsound('y'); successfully. The analyze('y'), however, didn't seem to do anything really.<br><br>Allan, the sndfile toolbox looks useful if you have files that you don't want to transcode, thank you.<br>
<br>I'm new to analyzing sound spectra and am lost on how to go about doing it in scilab. Can anyone recommend helpful references?<br><br><div class="gmail_quote">On Thu, May 27, 2010 at 3:32 AM, Allan CORNET <span dir="ltr"><<a href="mailto:allan.cornet@scilab.org" target="_blank">allan.cornet@scilab.org</a>></span> wrote:<br>

<p class="MsoNormal">I'm new to Scilab, and I'm having a difficult time figuring
out how I can analyze the signals in these mp3s:<br>
<br>
<a href="http://www.archive.org/details/ird062" target="_blank">http://www.archive.org/details/ird062</a><br>
<br>
How would I go about this? Is there any way I import the file without requiring
it to be a .wav file? I have converted, but I'd like to not lose in a audio
quality through transcoding it from an already lossy format.<br>
<br>
I did convert it to .wav to see if I could use wavread and analyze, as
mentioned at <a href="http://cermics.enpc.fr/%7Ejpc/mopsi/doc/ch19.html" target="_blank">http://cermics.enpc.fr/~jpc/mopsi/doc/ch19.html</a><br>
<br>
Wavread told me "mget: stack size exceeded (Use stacksize function to
increase it)." So, I tried <br>
<br>
y=wavread("test.wav", [1 5]) <br>
<br>
That made it not complain, but I'm not sure what that does.<br>
<br>
analyze(y) and mapsound(y) complain that y is an undefined variable after what
I thought was already assigned above.<br>
<br>
I need a decent overview of how to work with audio in Scilab and hope someone
here can help.</p>
