Free Multi-Band Correlation Meter

US Voxengo's Correlometer checks for the presence of out-of-phase elements in the mix 03/01/19

Voxengo describes Correlometer as a free analog-style stereo multi-band correlation meter AudioUnit, AAX and VST plugin for professional music production applications. It is based on correlation meter found in their PHA-979 phase-alignment plugin. Here's the details in their own words...

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.
