But the md5 are identical only if the audio are the same.
I would to record the word "computer" two times and be able to obtain true comparing the two file audio.

I will try to "Sum them in mono and invert the phase of one of them. If they fully cancel (you get no sound at all) they are identical."
How can i do that? There is a program on linux terminal?

If one "sounds" like the other, if they are enough similar.

It's possible compare two files audio? If yes, how?
An exmple:
if [ audio1 == audio2 ] ; then ....

Thanks to all!
