Sound Radix Announce Auto-Align Post 2

NUGEN Paragon ST

Sound Radix announces Auto-Align Post 2 an upgrade to the acclaimed and Emmy award winning Auto-Align Post plug-in.

Since its introduction in 2018, Auto-Align Post has helped deliver outstanding sounding dialogue in countless award-winning film and TV shows, saving editors days of tedious work. It has become 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 major step further by introducing a new Spectral Phase correction module, bringing further improved algorithms and UI, adding ARA2 support for compatible DAW’s  such as Nuendo and Studio One, and more.

Features At A Glance

  • 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

What’s New in Version 2

  • Spectral Phase Correction Module: In an effort to deliver a clean recording from a location set, a recorder may engage a high-pass filter on the boom mic to filter out low-frequency rumbles such as street or AC noise. However, electronic high-pass filters induce a phase shift to the signal, which can result 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]: Provides a detailed multi-band frequency correlation view.
  • Improved Algorithm: Auto-Align Post’s core algorithm was further refined to deliver better overall results.


  • Price for new users: $399
  • Upgrade price for current owners: $99
