What 2BC multiCORR does
A plain stereo correlation meter shows one overall value, which can hide problems that sit in a single frequency region. A fat kick or bass that is mostly mono can keep the overall reading looking healthy while another band cancels out when the mix is summed to mono. 2BC multiCORR splits the correlation measurement across 31 bands with carefully chosen center frequencies, so each region can be read on its own.
Five monitor controls are built in: Left Only, Right Only, Mono L+R and Diff L-R, along with the stereo balance correlation.
The developer states that the plugin combines the 2BusControl monitor controller with the multiband correlation meter, and that all MAAT products follow guidelines aimed at creating tools for modern engineers. The power features sit behind a clean interface, and the monitoring modes are arranged for quick switching during mix checks. Stereo noise, which is decorrelated with no similarity between channels, reads differently from a stereo music signal, and the 31-band display is meant to show that difference region by region.
Key features
- 31-band correlation meter. The correlation measurement is split across 31 bands with carefully chosen center frequencies, so a problem in one frequency region can be seen without being averaged out by the rest of the spectrum.
- Five monitor controls. Left Only, Right Only, Mono L+R and Diff L-R are included with the stereo balance correlation, so each monitoring mode can be switched on without a separate plugin.
- Stereo balance correlation. A stereo balance correlation view is included alongside the band display, covering the balance between channels in addition to their relatedness.
