Hi,
for some illustration (!) purposes, I would like to convert a time-frequency
array (originating from a time series of spectra f(wavelegnth)) into an
audible sound clip, e.g. a WAV file. I quickly looked at what's available
under numpy/python (http://wiki.python.org/moin/Audio/, or Audiolab), but I
couldn't find a single procedure to do this conversion.
Disclaimer: I don't know anything about sound processing, and this is just for
fun, similar to what has been done there:

Any hints or links on how to do that in a simple way?
Cheers,
--
