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.

New in Version 2:

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.


  • Microphones 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.
