What are Affordable or Free Sound Wave Analysis Software Options?

[Murky]

Hey :)

Do you know any sound wave analysis software? I'm especially interested in freeware or quite cheap ones. I can't use such stuff like Matlab or Cooledit (as I've heard which now is called Adobe Audition ;) ).

Greets,
Murky

Might Sonic Visualiser provide what you're looking for? It's released under the GNU General Public License, and is available for Linux, OS/X and Windows.

There's a freeware tool I've used called Spectrum Laboratory.
