It is a very interesting program for analyzing audios; developed from the Queen Mary University of London, it has also a good documentation and some tutorials.
Unfortunately I don't know if it is possible to make it portable, since I'm not a programmer.

Was about to suggest Sonic Visualiser and found this old thread when I searched the site. Thought it was easier to just bump it rather than start a new thread, as all the info in the OP is still accurate.
Cheers!
