 Re: Phase. What exactly is it?
Phase problems occur when more than one microphone picks up a particular source.
The sound hits the 1st mic, then a moment later (due to the speed of sound in air) hits the 2nd mic. These signals being slightly out-of-time do not add together nicely, and you get comb filtering type effects where some frequencies are boosted and some are cut and you lose the natural sound. Because the distortion is wideband it can sometimes be a hard kind of distortion to easily pinpoint, sometimes cymbals sound kinda wooshy, and sometimes things just don't sound natural and right overall.
The 3:1 rule is a good guide. If you have a mic 1 ft from the snare, there should be no other mics within 3 ft.
