I'm still trying to understand the Pros & Cons of Out Of Phase recordings. When is it good, when is it bad? Most of all "what is it?. Is it a cancellation of sound when picked up by two sources? I own a few C.D.'s by major artists where the cymbles are white noise & cancelling each other out. Is that what your trying to avoid? I more concerned about recording my guitar cabs with two mics. I just use two sm57's & blend them together. Can out of phase happen with this. Do some people like things out of phase? Any advice or opinions would be insightful.
