Graphic compare two sound events

Post Posted: Sat Jun 17, 2017 1:06 pm

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 ?

May be more like a Jack of all trades (and master of none). Confused
