Voxengo has announced the release of an update to the Correlometer analog-style stereo multi-band correlation meter based on the correlation meter found in the PHA-979 phase-alignment plugin.

Version 1.4 adds Apple Silicon native compatibility. The “asynchronous drawing” window mode has been enabled on macOS, which may fix the user interface “lagging”. Additionally, the AudioComponents interface has been added to the AudioUnit as the “.rsrc” interface may be deprecated in the future.

Multi-band correlation metering 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 is available to download in VST/VST3, AU and AAX plugin formats.
