Quadtracking is useless to me, so is double tracking... My playing is so tight that the waveforms always end up identical, I have to have 9 beers before I record to get any sort of stereo spread in my recordings....
What If you have to different guitarplayers.
Dual tracking: each player records 1 or 2 same takes?
Quad tracking: each player records 2 or 4 same takes?
Its alot of work to do dual tracks with two guitar players...
you *could* quad track that song, with your 2 takes guitar tracks. split the audio tracks into their riffs. duplicate the track, then re-order similar riffs. its a terrible hack, but it should work.
9 times out of 10, the riff or part is repeated after itself or in another part of the song - you can take that part from the original track and put it in sync with the same guitar part from a later/earlier part in the song, and it will be "double tracked."
IE:
gtr1: 1 2 3 4
gtr2: 1 2 3 4
1,2,3,4 represents 1 riff repeated 4 times, and it's currently doubletracked. You'd chop it up and move things around to look like:
a = original, b = new track made from chopping/moving the riff. You now have a "quadtracked" version of the same riff, but you never actually quadtracked the song with the guitarist(s).
The problem with this method is that the players aren't always tight enough in the repeats of their riffs to have it match up as tightly as you'd want.
