Filter the same sounds of two audio files

Hey guys,

I’m new to this forum and I am not sure if this is the correct subforum. But I hope it is.

Anyway, I have two audiofiles: Both are songs, both with the same vocals, but with different beats. The vocals are EXACTLY the same: Same time, speed, pitch, you get what I mean. It’s just that they use different beats.
Now I’m wondering, is there a way to filter out only the sounds of the two audio files that are the same? So that I end up with (almost) only the vocals?

Looking forward to helpful replies!
Thank you!


Previously I would have said “no, that won’t work”, but given some relatively new developments, I have an idea that ‘may’ work to some extent. To enable us to test, could you post about 5 or 6 seconds of both songs, with the same vocal in each. Export the samples in WAV format. Short WAV files may be attached directly to forum posts. See here for instructions:

Of course!
By the way, the song is “Love Letters” by Watsky!

This is a mix of the two tracks after applying “vocal isolation” with this effect:
