Fons:
Mentioned recently on list: http://sourceforge.net/projects/dsptools/
(something i need to look into further).

Similar capabilities might be found in AudioLab:
http://www.ar.media.kyoto-u.ac.jp/members/david/softwares/audiolab/
It's based on Numpy and libsndfile. For example, I used it to run the
small python script
http://soundviewer.svn.sourceforge.net/viewvc/soundviewer/svt.py?view=markup&pathrev=1

Guillaume -- Thanks for posting this!
The demo of TimeSide at http://crem.telemeta.org/ is especially interesting.

Just wanted to let you know that we might be working on similar
things, undoubtedly with different platforms and perspectives... I'm
using Java although it's nicely hidden beneath open-source tools like
http://xwiki.org http://groovy.codehaus.org/
http://velocity.apache.org and
http://code.google.com/p/simile-widgets/ and a non-opensource part
predicated on Flash being available in the platform web-browser, and
http://www.longtailvideo.com/players/jw-flv-player and of course
hidden deep underneath http://omras2.org/SonicAnnotator and
http://vamp-plugins.org/ ...

I'm working to get this setup publicly (pre-alpha) on
http://trainspodder.com , but for now, here's a few browser
screenshots:

http://nielsmayer.com/xwiki/bin/view/Exhibit/NPRpods3
is a working example of some navigation/search/flashplayer-media
playback aspects of above.
http://nielsmayer.com/xwiki/bin/view/Timeline/NprTimeline
is some much older working-prototype code. (nb: requires flashplayer,
and doesn't seem to work on KDE's konqueror, unfortunately).
