Auto-Align® Post 2

Since its introduction in 2018, Auto-Align Post has helped deliver outstanding-sounding dialogue in countless award-winning films and TV shows. It saved dialogue editors days of tedious work and became an essential tool for many audio-post professionals.

Enabling dynamic time-alignment correction of moving location microphones, Auto-Align Post makes it possible to effectively mix the boom and lav microphones by eliminating comb-filtering and phase artifacts caused by the time-of-arrival differences, with just a few clicks.

Auto-Align Post 2.1 takes an extensive step further by introducing a new spectral phase correction module, refined algorithm, and user interface. It brings native Apple silicon support for ARA2-VST3 in compatible DAWs, and Adobe Premiere Pro extension compatibility. A new Adobe Premiere Pro extension is now included along with AAX for Pro Tools and universal ARA2-VST3 plugins for compatible DAWs such as Nuendo, StudioOne, and others.

Spectral Phase Correction Module

A production sound mixer may often engage a high-pass filter on the boom mic to filter out low-frequency noise on-location recording sets. However, electronic high-pass filters induce a phase shift to the signal, resulting in a significant loss of low-end and ‘body’ of the dialogue when mixed with a non-filtered mic.

The new Spectral Phase Correction module detects and dynamically corrects frequency-dependent phase shifts to achieve significantly improved spectral alignment and richer sound.

Improved Algorithm

Auto-Align Post’s core algorithm was further refined to deliver better overall results.

Spectral Correlation Meter [AAX]

A spectral magnifying looking-glass provides a detailed 28-bands frequency phase correlation view.

ARA2 Compatibility

Long in the making, Auto-Align Post 2 brings VST3 support for ARA2 compatible DAW’s such as Nuendo and Studio One.

Native Adobe Premiere Pro Compatibility

Leverage all features of Auto-Align Post 2 inside the Adobe Premiere Pro interface.

I used Auto-Align Post on the first season of Bridgerton with great success. Now we are in post on season two. I could not imagine doing a show like this, with several booms and radio mics without Auto-Align Post. It’s a life-saver in dialogue editing!”
