I need an algorithm (a sample program code if possible) to compare sound patterns from two files(.wav or .mp3)..

I wish to build an application in c++ which will take two source files as input and compare them whether they are equal.

I searched the internet but did not get an algorithm.

  • What do you mean by patterns? if they are 100% equal? – Ofer Haber Apr 30 '14 at 13:43
  • I don't think you want to check for *exact equality*, because that would be trivial. You are searching for a certain degree of *similarity* between two audio files which a human listener would recognize as the same sound. This is a really complex problem. – Philipp Apr 30 '14 at 13:44
