I don't know where to place this so i put it here. It's about Phase cancellation.
Note: This post is not about plugins, Just a common basic The Physics of Sound.
Phase cancellation is generally something to be avoided when working with audio, but it can also be taken advantage of for its ability to isolate differential signals within two otherwise-identical mixes.
When two identical signals are perfectly in phase and played together, they double in volume as they reinforce each other. If we then shift the phase by a degrees until it hit 180 degrees(full half cycle), the two signals cancel each other out completely, resulting in silence.
For better understanding please read about
Wave interference
When abuse phase cancellation to some degree.
I make experiments long ago (4-5yrs) it's not perfect 100% but it show how destructive the wave interference can do.
