“It is good to use as few mics as possible. For example, when doing background vocals with three singers being recorded to one track, the result with multi-miking is phase cancellation and cone filtering (a ‘moving’ frequency response). If the singers are good and can balance themselves, one microphone yields the most desirable sound. By utilizing a cardioid polar pattern you can attenuate louder vocalists by positioning them more off axis.”
