Phasing problem advice

[DJRECORDS]

Hello DUC people,

We are just doing some quick mastering on our mixes and we have the phasescope plugin on the master bus and it says there is a phase issue? it says the phase is to the right/+1 on the plugin phase line. can we do anything this and is it a problem!

where is it that you think the indicator should be? and why have you jumped to the conclusion that this is a phase problem?

I think the indicator should be in the center? but it is way over to the right, on the phasescope plug its labelled +1. On the Waves Dorrough meter it also shows a phase to the right of the meter and the phase light comes on.

Hi,

Most likely something in the "mix" could be a mic on the hi-hat or under snare mic being out of phase with the main snare mic or guitar cab mics being close and not phase flipped etc. or if its not live instruments with mics then it could be some stereo widening plugin or something funky going on with layered samples you may have used in the mix.

you could bounce a test tone and then load that into your mastering session and check that, just to eliminate its not a problem with your system or routing, like a cable etc. if a pure tone is showing out of phase then you could have a problem somewhere in your signal path.

If it sounds all right then don't worry.

at least i tried to get the OP to figure this out on their own!
seriously, not only rtfm, but .... nevermind.

The Phase Meter indicates the phase coherency
of two channels of a multi-channel signal.
The Phase Meter is green when the channels are
positively out of phase (values from 0 to +1) and
red when the channels are negatively out of
phase (values from 0 to –1).
At the center or zero position, the signal is a per-
fect stereo image. At the +1 position, the signal
is a perfect mono image. At the –1 position, the
signal is 100% out of phase.rtfm

yes, lets just close down all the forums and tell everyone to the read the ....... manuals

Well according to the manual then we have a near perfect mono image but we don't the track is very stereo!!

Anyway the question was what if anything should we do about it? even now we RTFM the manual gives no information as to whether we should be concerned at all or whether to just close our eyes and forget the meters.

There's nothing we can think of in the mix that would cause this.

A +1 indicates complete correlation between the Left and Right, 0 indicates uncorrelated signal (i.e. two unrelated signals), -1 indicates out of phase. On typical mono-panned stereo mixes you would expect strong correlation between the two channels, on something like a stereo-pair recording of orchestra you will see much less correlation between left and right depending on the particular mic technique used. If you see tendencies toward -1 it's likely you have a phase problem.

Phase meters are useful for pointing up problems - even more so are lissajous display scopes - but really, an experienced ear needs to be the final arbiter. It sounds to me like you might want to be using an engineer with real-world experience for a while until your engineering chops are better.

All the best,
