Basically, if you have:
Sound 1: A sound (bass, guitar, vocals, ...)
Sound 2: A beat with that sound on it
...you can get the clean beat out of sound 2.
I tried it with "Untitled Heavy Heat, Pt. 1 & 2" by DJ Shadow...
I sampled the beat with the bassline on it, ...
...sampled the bassline itself (from the beginning of the song) and...
...got the cleaned beat! It sounds amazing despite the loss of the low end.
Of course it works best with sample/loop based music, because the results are only decent if sound 1 appears similar in sound 2. And in sample-based music that's neccessarily the case.
I wonder if there are similar plugins to compare it with...
However, breakbeat cleaning seems to have come to a new level
