An old widely used method to remove voice from any music track was to subtract the channels from the right channel you must subtract the left channel and you would get the audio output without the voice, the background sound.

However that method produces poor results as with it you will obtain a mono output with no bass. As expected the mix sounds real bad. This worked only on older type of tracks and you couldn’t really isolate the voice you could just remove it.

Voice trap offers two sophisticated DSP algorithms:

• FFT-based center channel suppression / isolation
