Correlometer is an analog-style stereo multi-band correlation meter plug-in based on the correlation meter found in the PHA-979 phase-alignment plugin.

Multi-band correlation meter is an advanced way to check for presence of out-of-phase elements in the mix. Broadband correlation metering reports overall phase issues and may misrepresent problems present in select spectral bands, while multi-band correlation meter easily highlights problems present in mid to high frequencies that are not easily heard by ear, but may still reduce clarity of the mix. Another application of multi-band correlation metering is phase- and time-aligning of channels and tracks, especially bass and bass-drum pairs, guitar mic and D.I. source pairs, two-microphone stereo recordings, etc.

Correlometer can display 4 to 64 individual spectral bands, with adjustable band quality factor that controls the degree of band's selectivity. Averaging time of correlation estimator can be adjusted. Correlometer supports side-chain inputs for easy correlation estimation between separate audio tracks.

Correlometer features:

• 4 to 64 band correlation meter.
• Adjustable band quality factor.
• Adjustable averaging time.
• Side-chain input.
• Resizable user interface.
• All sample rates support.
• Zero processing latency.
• User interface color schemes.
• Retina and HighDPI support.
