“MetaCore” is an intuitive correlation meter which shows how much your signals are in-phase or out-of-phase.
The device not only detects out-of-phase signal problems but also gives phase manipulations options to help in fixing them. PAN and WIDTH controls are also included for further tweaking of your signal.

Correlation meter is one of the “must have” utilities for mastering, pinpointing issues with stereo or mono signals and helping in controlling and fixing “out of phase” problems.

Correlation value “+1” indicates that L/R channels correlate 100% (signals are in phase). Maximum correlation (identical signals).

Correlation values to the right of the center position (“-0.99”..”0”) indicate that the stereo signal is mono compatible.

Middle position “0” indicates the highest value of L/R divergence, which is audible as a wide stereo effect. No correlation between the signals.

If the Correlation meter moves to the left of the center position, out-of-phase material is being detected. This leads to phase cancelations (if the stereo signal is combined into a mono signal)

“-1” minimum correlation value indicates that L/R signals are completely out of phase.

The right half (from 0 to +1) is shaded green, the left-half (from -1 to 0) is shaded red.

If using a dual-mono signal just invert one channel’s polarity to make the signal “in-phase”.

PHASE INVERTOR MODES:
- NO (phase not inverted)
- LEFT (invert left channel phase)
- RIGHT (invert right channel phase)

This looks great. I might grab it right away because I'm in the middle of a project whose client wants a "wide screen" feel and keeps telling me "wider! wider!" and may not be realizing all the implications. :-)

It occurs to me you might be leaving money on the table by saying "mastering" as opposed to "mixing and mastering". It seems one could drop this into a mix in a lot of different places to find out where problems arise and potentially fix them before they are allowed to propagate and thus become unfixable.

I already have Reasonistas Corelation, but if not, I would pick this up right away. Nice price also.

Most users think the reason their requests aren't being met, is because some developer somewhere in a cubical refuses to waive its magic wand.

I have that as well, but I rarely think of using it. I can't quite put my finger on why…

Grabbed it ......... still not sure how these things work though! :oops: I just strapped one on my master output chain of devices.

Put a Rex loop through it. It's jumping all over the place. I need to do a bit of reading and research to se what this is all about! :shock:

I may have figured out why I don't use CoreReLation Phase Analyser. I think the the cognitive load is too high. The visual impact is too great. Also, is it a diagnostic or utility? It's a floor wax and a dessert topping. I want to like it. I should like it. It does All The Things in a single RE, which ought to make me love it, right? It seemed like a good idea at the time. I obviously bought it and I don't exactly regret having done so, but let's just say there is an undeniable lack of evidence that I reach for it. So I'm trying to analyze that without flinching.

Also I am obviously a hypocrite because I love love love Ozone Imager, which has some of the same virtues and faults and yet I can hardly wait to experiment with it on just about any track despite its also being a VST and my strong preference for RE. (And yes I'm aware there's a multi-band variant in Ozone proper… Don't get me started…)

If I weren't such a terrible hypocrite then I suppose I might also be contemplating combining METACORE with the also-brand-spanking-new (and free) Stereo Converter. Oh, hey, I am contemplating that. Maybe I am not such a terrible hypocrite after all.

I also wonder how my ongoing attachment to Stereo Splitter will be affected by all of this.

@ Faastwalker
This kind of utility can be usable at master just to check and find places with our-of-phase material in mix, places that usually can work bad role in the whole mix.
Modern music today is much more coming to wider mixes.

It very cool if you can create from simple track beautiful stereo product. We all know how sad can sounds bad mixes on the great material.

But you must start from single tracks to check..
Just a guitar in mono, or bass.. that can be very limited in stereo picture is working nice?
Or does is your stereo track have in-phase signal?

You can find phase inversion at Reason SSL mixer, but not have basic correlation meter with withal part.

You can fix any flat tracks by inverting phase of one channel and make nice sound for this track in mix.
No needs to use stereo widening, but you also can with this RE, or using any additional creative FX for instrument to make sounds better.

Just try to listen, look at meter for some tracks, and you can get cool results from previously flat tracks on mix without global changes of track

Cool to use in various scenarios, very helpful for fast checking and fixing out of phase material.

Just Google something about role of correlation in the mix, it’s usually very short talks but helpful.

May be my fault that I not attach audio examples and need to make them, but it’s just the meter with out-of-phase fix and pan, width image possibilities

Just bought this a few days ago. What a great tool to check on some issues before they happen!

I'm doing some tests on various Phase meters. Metacore seems to be giving me the exact opposite to every other meter I am testing (see image). So when the others show plus numbers, Metacore shows minus numbers.

I don't have this one (expired demo) but I think I have tested all the others:

What is going on here? Thanks.

Hello, dioxide.
Thank you for your attention.
We start on this RE as De-Correlation utility. Bat at last moment try to invert it to classic Correlation meter. And make some GUI troubles. You are right, currently RE show inverted +1/-1 positions.
I now out from the work for 2 days, but soon as possible (I already start fixes time ago) try to resolve this problem for better understanding from GUI side.
Answer for current version is Decorrelation mode. Sorry, but this must be fixed soon as possible, because this all really non-intuitive
