MAAT 2BC multiCORR v1.1.6-R2R screenshot

Why do you need a multiband correlation meter? Broadband meters don't always show you potential trouble areas. MAAT's multiband approach warns you not to overdo stereo spread, or when your stereo room mics are delivering too much out–of–phase content. Either way, you'd get cancellation when your mix is summed to mono.

Correlation measures the degree of relatedness between left and right channel. If both channels are alike, that's mono, and they will have perfect correlation. When content is present in one channel, and an inverted phase version is in the other channel, that sums to zero in mono and the audio disappears.

If your material is destined for LP distribution, keep in mind that lacquer cutting has difficulty with large amplitude, out–of–phase information at very low frequencies. 2BC multiCORR provides four bands of analysis for the critical bottom octave, six additional bands of metering covering frequencies up to 200 Hz, plus three additional band for the 200 to 400 Hz range.

Other than vinyl, why should you care about mono? Monaural playback is more prevalent than ever, with the rise of battery–powered, hand held party speakers and the ubiquitous "smart speaker." Don't forget that Center Channel speaker in a surround setup...Though a product may advertise stereo playback, the simply fact is that size matters. At low frequencies, playback from any single point, diminutive device is essentially monaural. Also, small sources usually cannot reproduce the bottom octave at all and many begin to roll off below 100 Hz. So make sure to maximize the appropriate amount of LF energy for the material you're working on.

2BC multiCORR isn't just multiband correlation. It also includes a left/right balance meter, a broadband left/right correlation meter, plus five monitor controls allowing you to focus on any issues you may come across.
With a single button, you can switch to Left–Only or Right–Only, Mono (L+R) or Difference (L-R). The fifth monitor control, FLIP, swaps the left and right channels. Sometimes you may come across a subtle issue that you think may be in one channel or the other. The Flip control, along with the Left–Only/Right–Only buttons, quickly helps to confirm or identify any problems. Also, you may occasionally be presented with a mix that's not laid out from the audience prospective, and Flip is a quick way to rotate the soundstage around to where you're comfortable.

Most correlation meters use a cosine scale, derived from old analog meters, while 2BC multiCORR employs a trueLinear scale. A linear scale better matches your perception.

2BC multiCORR combines essential metering and monitor controls with a 31 band correlation meter group.


31 bands of correlation with carefully chosen center frequencies.
Exclusive trueLinear scale for higher precision with visuals that match your perception.
Stereo Balance and Correlation.
Five essential monitor controls: Left–Only, Right–Only, Mono (L+R), Diff (L-R) and Flip.
Collapsable UI lets you see only what you need.


Includes a native version that runs in standalone mode, great for dedicated metering.
Plug–in runs on all major DAWs: AAX, AU, VST 2 & VST 3.

* You need the installation of R2R-WAIFU.
* CodeMeter runtime installation is not required.
* Our release runs faster and uses less memory than legit version.

Cheers r2r + DECiBELLE
What can I use this for?
(In layman’s terms please)

Synth layering, vocal layering (lots of times, the synth layering doesn't sound as smooth as the real deal not only because lack of warmth or presence but because phasing issues, it has the character but in some freq ranges it just sounds weird like it doesn't "glue" not necessary because lack of compression/ saturation but because out of phase stuff. Also you can have a better mono or in phase correction than using a normal mono - wide knob because in this case you would be working in select ranges.

Come here just to try the software and buy it afterwards.
If I don't like the software I will just DELETE it.

Can anyone explain why this release might be better than for instance iZotope insight correlation meter? Why do we need a multi-band correlation meter?
  Member 9.11.2016 57 284
for fix specific freq
  Member 22.02.2015 204
Use this to identify frequency specific phase issues and fix them with their phase shifter plugin.

nice thanks

looks like great plugin..but i dont want install waifu, because of reason is my daw ;(
  Member 22.12.2018 288
I found it useful with estimating if I should use and the results obtained by Raising Jake SideMinder plugin. It turns out that sometimes you need more than just one pass with it.
And multiCORR also confirms that SideMinder does a real good job.

Thanks!!.... this seems to be a cheap copy of Voxengo Correlometer
  Member 22.12.2018 288
Voxengo is free, and this one is regular $49...

Such a usefull tool. Thanks!
  Member 14.03.2017 32 207
It's exactly the same than Voxengo Correlometer, but Correlometer it's under the prestigious of Voxengo ;)
