A common task when dealing with audio in a multi-mic recording
(e.g., of a drum set, piano, guitar, or a whole band) is to invert
the polarity of certain tracks to create a mix with the least amount
of signal cancellation. When dealing with a larger number of tracks,
this process can be difficult or practically infeasible (with just
10 microphones there are actually 210 = 1024 possible polarity
configurations!).

Polarity Maximizer is a multi-track plug-in that additionally
routes audio from several audio tracks to a single master controller
that analyses the audio and automatically sets the appropriate
polarity (in/out) of each track.

Simply insert the plug-in on each track, and the master controller
performs a one-time polarity analysis after playback. The method
uses a special signal-processing algorithm to determine the optimal
polarities (rather than rotating or affecting individual phase
characteristics of the audio) that also guarantees the maximum RMS
output level of the combined tracks. The controller automatically
sets the appropriate polarity (in/out) in the plug-in for each
track. After analysis, the plug-ins act only as a low-latency pass-
through of the polarity-corrected audio.
