01Overview

2BC multiCORR is built to show phase and mono-compatibility problems that a standard broadband correlation meter can miss. Its 31 bands let you see where in the frequency range out-of-phase content sits, such as strings or hi-hats cancelling while a mono bass and kick look fine. Alongside the metering, it includes Left-Only, Right-Only, Mono, Difference and Flip monitor controls, plus a collapsible interface that shows only the functions you need.

03In depth

Multiband correlation metering and the trueLinear scale

A regular stereo correlation meter shows the overall relationship between left and right, which can hide problems in specific frequency ranges. 2BC multiCORR divides the signal into 31 bands with carefully chosen center frequencies, so you can see which parts of the spectrum are losing energy when the mix is summed to mono.

Most correlation meters use a cosine scale inherited from older analog meters. MAAT uses its own trueLinear scale instead, which the developer says better matches how the meter reads to the eye. The plugin also adds a stereo balance meter and a broadband correlation meter alongside the multiband display.

Monitor controls for checking stereo problems

Five monitor controls sit within the interface: Left-Only, Right-Only, Mono (L+R), Diff (L-R) and Flip. With Left-Only or Right-Only you can isolate a suspect channel, while Flip swaps left and right to help confirm where a problem originates. Flip can also rotate a soundstage that was laid out from the wrong perspective.

The interface is resizable and can be collapsed to show only the meters you are working with. It can be placed in the last slot of a master bus, or run in standalone mode as a dedicated meter.

05FAQ

Questions, answered

What is 2BC multiCORR used for?

It is a correlation meter for checking how stereo content will behave when summed to mono. The 31 bands help you locate frequency ranges where out-of-phase content could cancel, which is useful during mixing, mastering and post production.

Which formats and operating systems does 2BC multiCORR support?

It is available in VST3, VST2, AU and AAX formats. It runs on Windows 7 and newer (32 and 64-bit) and on macOS 10.9 and newer as a 64-bit Universal Binary 2. Sample rates from 44.1 to 384 kHz are supported.

What do I need to use 2BC multiCORR?

It runs as a plugin inside a compatible DAW that supports AAX, AU, VST2 or VST3. For AAX, the listed requirement is Pro Tools 10.3.10 or newer. A native standalone version is also included for use without a host.
