I have an audio file that contains multiple sound events of a fraction of a second that appear identical when listening in headphones.

I would like to be able to visually compare two samples so that I can see if the graphic representation is really identical.

Based on some Google searches, the comparison technique should be called acoustic fingerprinting.

Is there any software (better if free) that I can use for my need ?
