Cool thanks for that. I've been struggling with doubled vocals. Harmonies too. Anyone got tips for those?
I never double a harmony, but you could using the very same technique.
Here's my process:
Main vocal: I never copy or clone a vocal. I record THREE main vocal tracks all exactly alike.... or as close as possible. I select one to be the main and the other 2 become the doubled tracks. The doubled tracks get spread 100% right and left. I drop the levels down on the doubles about 12dB or so. You should be able to hear the doubles when the tracks are soloed but not so much when in the mix.
Harmony vocals: I record one high and one low or whatever else I want. I pan these about 40% right and left and drop them about 16dB below the main vocal track.
NOTE: the amount I drop the doubles and harmonies will vary depending on what sound I'm trying to achieve. I like the subtle harmony that almost sounds like it's part of the lead singer's voice and not a "Statler Brothers" kind of in your face harmony.
EQ cuts, compression and reverb are all to taste.... remembering that quite often, less is more.
