Can one have an issue with phasing (such as phase cancelation) and be unaware of it ?
Does phase cancelation create any sort of added color to the sound which makes it detectable or is it a pure and clean reduction in gain ?
If the later is true, how can we tell we a phase cancelation problem ?

phase can definitely color sound (sometimes in a pleasing way). youll know phase when you hear it, it sounds hollow (like running a guitar amp through a pipe). mess around with delays (double a track and set a delay on one, run both mono) with 1ms, 2ms, all up to 80 or so. youll hear a major difference between 1 and 4, and it fades away the higher you go.

Multiple signals are almost never completely in phase with each other, it actually adds to our perception of a stereo image, unless it's so far out that cancellation becomes a problem. Typical phasing problems are overheads on drums, piano mics. Check the pairs in mono, and listen for things going away. It's fun to listen to a Hendrix record in mono, amazing how much goes away :)

Thats intreasting... Im curious to know how and when you realized this ?
