I wanted to take ONLY the parts of a stereo mix which lie right in the middle. It would be basically the inverse of a stereo difference effect. <br>
<br>To put it another way, Stereo difference removes those parts of the mix which are panned dead center. What i want to do is leave those parts, and then remove anything that isn't panned dead center.<br><br>At first, i thought it would be as simple as just subtracting the stereo difference signal from the original mix. But when i actually tried it, it didn't work, and then also when i worked it out logically on paper, i realized that it's impossible just with simple arithmetic. <br>
<br><br><br>My best guess, is that you could FFT the stereo difference signal to get it's spectral profile, and then subtract that from the original mix. Might give it a go some time.<br>
