Remove ambience from a music with ambient file by Mygoshi at 9:23 AM EDT on July 24, 2017
Hello I ripped Iron man 2 XB360 version unfortunately music contains ambience, but I found out that those ambiance only are also available without music. I tried invert phase in Audacity to remove that ambience in music but does't work, the amb is still here. Any ideas? Thanks in advance.

Post samples of the ambience only track and the music track with the ambience in it.

It should be obvious, but the invert phase, would only completely eliminate the ambient sound, if the ambient sound is precisely the same. If however, the ambient sounds are not precisely the same, they may not completely cancel out. I.e. one might have an amplitude of 0.9, but the other an amplitude of 0.95, which means they'll have a resulting amplitude of 0.05.

Sometimes, this can be pretty much perfect, for example, I took the miniusf file of Toad Town from Paper Mario, and the miniusf of the Toad Town (Fighting Dojo) variation. Inverted them, and this is what happened: https://www.youtube.com/watch?v=HdFZR4J0oqo
Literally no trace of Toad Town remaining.

However, other times, parts of what you want to be removed, will suddenly appear randomly, because there are slight differences in the samples for literally no reason.

Yes I noticed it was a bit different O_o thanks for the clarification. So I think I'll remove the files from this game of my computer, and ... fortget about it ? Ambient sounds clearly destroy the track, so, yeah. It's not a good track though but I talk about the others. At least PSP rip AT3 doesn't contains amb...

A convolution based noise reducer may also be able to remove it, if the ambient sound is something you can isolate, and it's something constant and mostly unchanging throughout the audio clip.
