Sonic Visualiser is an awesome program for audio files analysis. It's completely free - on GNU license. It can be useful for some more advanced guitar pedal and amp makers.
It is a very expanded software, with a lot of ways of sound visualisation (spectrograms), comparison and track marking. The interface is intuitive and easy to learn.
The program is available on Linux, OS/X and Windows.
