I want to know how it's possible to substract one audio track from another. Meaning that you cut out the frequency spectrum of a audio file from another.
I know how the phase inversion trick used to create diy acapellas, but what I want is to substract a track from another that have nothing in common.
I think there are a few denoising programms, that let you input a sample of the noise to be removed from a recording, so I guess it would be something along those lines?
Would be very glad if someone could tell me how to do this and which application to use.
