MetaCore Correlation Meter

“MetaCore” is an intuitive Correlation & De-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 meter mode show the stereo signal value between the Mono Compatible and Mono Compatibility Risk.
De-Correlation meter mode show the stereo signal value between the Mono Compatible and Stereo activity

Correlation mode

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

Position lower than “0” (left of the center position “-0.99”..”0”) indicate that the stereo signal is out of phase.

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)

Correlation = “-1” 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”.

De-Correlation mode

De-Correlation value “+1” indicates that L/R channels of the stereo signal is out of phase. Signal is support stereo compability between the L/R channels.

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

Position lower than “0” (left of the center position “-0.99”..”0”) indicate that the stereo signal is in-phase and based on Mono-Compatible material in both of L/R channels.

Other Controls

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

PAN: set L/R channels Pan for the incoming signal

WIDTH: Width control of the signal.
Linear narrowing of the signal from stereo to mono. Extra Widening of the signal (from 100% to 150%)

UPDATE 1.1.1:

• Now device works as meter in Correlation and De-Correlation mode
• Bugfixes
