How to test if two audio files are identical?
Invert the phase of one of them.
( When two identical frequencies are cycling 180° opposite each other, complete phase cancellation occurs)
How?
In the DAW (Digital Audio Station) Reaper, there is even a small button to invert the phase of each track individually.
Align both tracks and test.
In this example, both files are identical, so you get digital silence in the master track, although each individual track gives sound in itself.
For this test I used the track "All of the Above", by Brigida HB
