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.


By 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 takes a significant step further by introducing a new spectral phase correction module, refined algorithm, and user interface. It brings ARA2-VST3 support for compatible DAW’s such as Nuendo and StudioOne, and more.


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.


ARA2 Compatibility

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


Spectral Correlation Meter [AAX]

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


Improved Algorithm

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