I am interested in various methods, used by pro sound engineers to eliminate phasing problems with the sound at the mastering stage.
But I still haven't found any systematical description on this subjects.
Maybe someone could recommend some useful links in the inet for this, or just list several methods/technics being mostly used? All I know is mid-side recording technic but still can't imagine right ways of using it with the goal to avoid phase cancellation)
Phase isn't something to address at the mastering level. It's a problem to tackle during tracking or mixing. I also suspect there might be other important factors involved in your mixes, because phase is usually pretty subtle.
For multiple mics on the same source,
Delays on the several-microsecond level can sometimes bring your sound into better phase. You'll hear it become richer and fuller. I use this on situations with a house mic (>30ft from source) and a close mic all the time.
UA also makes a ridiculous little plugin that seems to help on the correction (giving you any angle, not just flip-phase). No experience with it.
For a stereo recording, you'll always have phase issues. MS is good at minimizing. For XY, get the mics as coincident as possible. With large diaphragm mics I'll often put one mic upside down and have the capsules touch. For ORTF and other techniques, accuracy close to the target angle and distance can help.
