About this plugin
MAAT's 2BC multiCORR addresses a genuine limitation in standard stereo correlation metering. While conventional correlation meters show overall L/R phase coherence, they miss problematic frequency-specific cancellation that occurs in complex mixes. This plugin divides the spectrum into 31 third-octave bands, revealing which frequencies are at risk of phase collapse when summed to mono - a critical concern for any mix intended for translation across playback systems.
The technical foundation is solid. Rather than adopting the cosine scale common to analog-era metering, 2BC multiCORR uses a linear scale that more accurately represents actual phase relationships. This distinction matters: it provides clearer visibility into the severity of correlation issues without the non-linear compression that obscures subtle problems.

The interface integrates correlation metering with five monitoring modes and stereo balance analysis, drawing from MAAT's 2BusControl monitor controller. This consolidation proves practical for mix engineers who need to diagnose phase issues without context switching. The design prioritizes clarity and quick problem identification rather than visual complexity.
2BC multiCORR serves mastering engineers, mix specialists, and anyone working with stereo sources prone to phase complications - orchestral recordings, stereo synthesizers, or heavily processed vocals. It's particularly valuable for engineers mixing in untreated rooms where phase relationships are difficult to hear.
Among correlation analysis tools, this plugin stands out for its multiband approach and straightforward execution. It fills a specific technical need without unnecessary features, making it a practical addition to professional workflows where mono compatibility remains non-negotiable.
