    Hey all, I tryed to follow this video to understand Phasing and test it...


    But it doest seems to read anything on my case.. here is how i have it set up.

    Audio track with base line
    another Audio track with exact copy of first (for comparison purposes)
    3th audio track with same base line but phase inverted.
    All bus sendt to an aux channel that works as master fader, this one with the PAZ- Analyzer plug in on it or Phase Scope.

    So when i have active 1st and second track (exact same base, none inverted) i hear the slight volume boost and analyzer shows all centered, when i have one of the normal base lines toguether with the inverted one, I clearly hear the sound reduction and low freq. desapearing so the phasing is clear, still the Analyzers shows everything centered and not giving any out of phase signals.

    My results dont show on the PAZ analyzer or Phase Scope plugins ANY badphasing areas at all, everything stays in the middle and i think I have done the same as in the video, any ideas why my analyzers not showing anything in oposite phasings when one of my base tracks i have complitely phase inverted?

    Thx

    Have you panned the tracks left and right? You need 2 speakers moving independently to hear the difference, If everything is in the center it's like you are in mono.

    Oh wait you can hear the difference but don't see it? I like the Durrough meters to check phaze. easier to see.

    Is your aux channel in stereo.
    You would have to send 2 sends one left aux and one right for.you to get a.stereo signal to it

    Yo chris, thx alot for the reply, yes basicaly i could hear the diff. but not see it... and by moving the pan buttons semmed to do the trick, sudently the metters started to show it. I still dont understand the reason but i guess google about phasing will do magic to understand it better ;O) Thanks alot.

    Phase is about 2 speakers moving forward and backward. If one is moving forward while the other is moving backward they are out of phase.

    If you don't have them hard panned left and right it will be harder to tell what's what as both signal get sent at the same time to both speakers.

    Imagine two wheels, each with paint marking a point on the perimeter, both spinning at the same rate. If the paint marks are lined up together they are in phase. If the paint marks don't line up they are out of phase by some number of degrees. If they are spinning at different rates they are continuously changing relative phase. When you have both channels panned center there is no difference between them to be measured, like the two wheels are welded together with the paint markings lined up.

    If your phase is exactly 180 degrees away from the original, so they cancel, they won't display on a phase meter because it is simply a gain reduction. For the phase meters in most software to work, they need a variable music source - like a mix. They compare two sources - usually left and right. In your case you are trying to use them to detect the wrong thing. If you route one of your channels, maybe the inverted one (which is not actually shifted in time, as phase is - it's shifted in polarity, which isn't the same thing) through an insert that takes time to process, your meters will reveal the phase error. A waveform inversion doesn't work.
