I've been thinking about using Perl to visualize audio (or in other words "convert" audio to a jpg, png or maybe even svg).
What would be the best way to extract audio from a MP3/WAV or other audio files and convert them into waveforms as graphic?
Converting could be done by FFMPEG, still, the clean export of such waveform seems to be more complicating than I've originally thought.
Any tips from you perlmongers ? Where to start ?
CPAN didn't really cast any light for this one ...
http://www.alharris.com/images/waveform.gif is an example of such waveform..
I'll be dedicating/collecting info towards this thread for any future topics around this since perlmonks seems to be rather poor (yet) around audio/visual processing...
Thanks in advance,
Wildchild
