MAAT 2BC multiCORR Multiband Correlation Meter Plug-In

MAAT 001B1 Overview

Find the hidden problems in your audio across 31 bands with the 2BC multiCORR Multiband Correlation Meter from MAAT. This versatile plug-in and standalone software uses comprehensive stereo monitor control and a trueLinear scale that matches human perception to eliminate trouble spots during production efforts.

In essence, this meter measures the degree of relation between the left and right channel, allowing you to find frequencies that may be cancelling out, something that cannot be detected via traditional stereo meters. Along with its useful and flexible correlation metering, 2BC multiCORR sports five essential monitor controls-Left-Only, Right-Only, Mono (L+R), Difference (L-R), and Flip for swapping stereo channels-as well as the ability to monitor both left/right and mid/side channels within the stereo field. Support for up to 384 kHz sample rates allows for a professional, high-quality production workflow. Compatible with macOS or Windows computers, 2BC multiCORR includes a standalone version and a plug-in version with support for AAX native, AU, VST2, and VST3 formats.

Applications

2BC multiCORR is a general purpose tool for both production and post. Use its powerful metering and monitor controls for:

• Tracking and Mixing
• Mastering and Remastering
• Sound and EFX Libraries
• Radio and Television Production and Broadcast
• Identifying Problem Elements EFX, panning, widening, or frequency ranges that may compromise playback or downstream processes
• Verifying: balance, panning, superstereo processing, and other creative decisions

trueLinear Scale

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

A Versatile Tool

If your material is destined for LP distribution, keep in mind that lacquer cutting has difficulty with large amplitude, outofphase 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 batterypowered, hand held party speakers and the seemingly ubiquitous smart speaker.

Don't forget that Center Channel speaker in a surround setup. Though a product may advertise stereo playback, the simple 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.

Not Just Correlation

2BC multiCORR isn't just multiband correlation, it also includes a left/right balance meter, a broadband left/right correlation meter, and five monitor controls allowing you to focus on any issues you may come across. With a single button, you can switch to LeftOnly or RightOnly, 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 LeftOnly/RightOnly 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 perspective, and Flip is a quick way to rotate the soundstage around to where you're comfortable. For extra versatility, 2BC multiCORR includes a native version you can run anytime to meter outside of your DAW or plugin host.

Note:

To use 2BC multiCORR standalone, you usually need a virtual audio device, an audio driver that provides a software device that the operating system can use for I/O patching.

Resizable UI

2BC multiCORR packs the advanced features you need into one resizable window that's easy on the eyes. Not only does the UI get out of the way, so you can be more productive, MAAT has incorporated user-centric features that speed up your workflow. Easy and intuitive to use, be sure to hang it off the last slot in your Master Bus so you always know exactly what's going on with your mix.
