What's The Difference?

Auto-Align and Auto-Align Post were designed to fix the comb-filter effect caused by multi-mic recording of a single source.

Auto-Align Product Family

Auto-Align® and Auto-Align® Post 2 were designed to fix the comb-filter effect caused by multi-mic recording of a single source, where the mics are placed at different distances from the sound source. When summed in a mix, the difference in time of arrival to each mic causes a phase shift that varies throughout the frequency range and cannot be fixed using a phase rotator. This article will outline the use-cases and features of both radical plug-ins.



Auto-Align


Auto-Align® makes static time adjustments which are more useful for stationary multi-mic recordings. It also has an internal phase-accurate SEND/RECEIVE routing system for aligning several mics on a drum kit, for example. Auto-Align also has noise floor sliders allowing you to filter out bleed from other drums, which can improve detection greatly.

Auto-Align® significantly reduces the comb-filter effect and effectively improves the resulting sound.



Features


-Automatic, sample-accurate time and phase alignment

-Phase polarity detection

-Alternate matching points for improving phase correlation while preserving delay

-Displays distance in samples, milliseconds, inches, or centimeters








Auto-Align Post 2


Auto-Align® Post 2 has both static (which is similar to the regular Auto-Align) and dynamic mode, which is more useful for dialogue and situations when the recorded elements such as the actor’s lavalier microphone, multiple on-set microphones as well as the boom mic are moving.

Auto-Align® Post 2 also includes a dynamic phase rotator.


Features


-Microphone time-alignment of up to ±100ms or distances of up to ~112 feet / ~34 meters

-Spectral Phase Correction Module corrects phase-shift caused by electronic and acoustic filters

-Dynamic mode enables continuous phase/time correction for moving actors or cameras

-Static mode enables fixed phase/time correction for stationary microphones

-Transparent

-Multi-channel support

-Spectral Phase Correlation Meter

-Highly optimized for CPU efficiency and operation speed

-Easy to operate - no manual adjustments required



For recording and mixing, we would generally recommend Auto-Align, for post-production, Auto-Align Post 2.
