Not an expert here, but I'll try to help. Phasing itself is really not the issue - it's really just a matter of describing where in its cycle a waveform begins. Phase distortion and phase shifting can have an audible effect and it's caused when several audio signals are combined at the input, but their relative phase is changed (e.g., due to a filter/EQ) before the output, which alters the phase of the relationship and can cause (usually minor) audible phasing effects.
The phaser effect that is commonly used on guitars, synths, etc. works on the same principal by splitting the incoming signal into two paths, and modulating the phase of one path to create the familiar sweeping phaser effect when the two paths are combined at the output. That's my understanding, at least. Maybe somebody smarter than me can correct/clarify this. |

pressure opposites that when combined, create nulls and peaks.
A dance track whose bass disappears or has nulls from out of phase stereo imagining. It affects how your track is hear in a room, it is pretty much a side effect what audio is so ya, breaking audio down to its most basic components is phase and phase issues.
What is causing the phasing ? THe microphone issue is not any different really than the issue you are dealing with.
2 signals will reinforce each other, or cancel each other out. Everything else is between those extremes.
It is sort of the first chapter of every audio book ever written. |

| This might not be what you're asking about specifically, but with certain synths at the beginning of a measure if you start and stop the MIDI clip on a synth it will be in and out of phase, which is really annoying. Especially if you don't like bouncing out. |

| same principle. 2 sound sources that are not in sync resulting in an oscillating beating if the signal is simple or phasing if the signal is rich in overtones. The ossilations will increase with pitch unlike comb filtering which will remain constant. |

| deadmau5 posted here a while ago regarding phasing, and it was pretty well put together |
