Phasing and not knowing

    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 ?

    Home Page:
    Take the 2 signals and run them both right up the middle...centered...instead of Left/Right. If there is a possibility of future phase cancellation problems in mixing or mastering you will find it right away by centering both signals.

    You can also find out by bouncing the 2 tracks down to one mono track.

    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.

    when you first start out it can be dificult to hear phase problems, especialy when doing complex mic technique's. ohe yea while we are on the subject of phase, both my HM1 (a matched pair) are out of phase.

    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 :)

    really.. i thought hendrix used a lot of stereo components (hard panned right clean guitar) and a lot of other funky panned parts.
