How to remove a drum track from a song mix by using a copy of the solo drum track, therefore creating a drum-less song or song without the drum track.

You can extract audio from the full track and remove the drums if you have a solo drum track.

Please note that in order for this to work, your separate drum track has to be an EXACT (sample accurate) copy of the drum track contained in the full audio track.

What you have to do:

1) Import the full audio track (that includes music+drums) to your music multi track recording software (Sonar, Cubase, Nuendo, Pro Tools etc.) and place it on track 1.

2) Import the solo drum track and place it on track 2.

3) Align the solo drum track (track 2) to the full audio track (track 1) by moving left or right down to the sample. Zoom in all the way, so that you can clearly see that they are sample-aligned.

4) Once you have achieved this, the magic will happen with a press of a single button "phase switch". Hit the "phase switch" button on your track 2 (it is usually found above the slider on the mixer). Magic! Drums have disappeared due to phase cancellation. Basically you have reversed the polarity (switched the phase) of the drum track against another copy of the same drum track and it cancelled itself out, leaving the rest of the mix untouched.
