Sound Radix has released v2.1 of its Auto Align Post video editing software with Adobe Premiere Pro compatibility, streamlining the workflows for users.

Sound Radix Auto Align Post 2.1Auto-Align Post enables dynamic time-alignment correction of moving location microphones, which makes it possible to effectively mix the boom and lavalier microphones by eliminating comb-filtering and phase artifacts caused by the time-of-arrival differences.

The last update (v2) took a significant step forward by introducing a new spectral phase correction module, refined algorithm and user interface. With v2.1, Auto-Align Post includes a new native Adobe Premiere Pro extension along with AAX for Pro Tools and universal ARA2-VST3 plug-ins for compatible DAWs such as Nuendo and StudioOne. The update also brings M1 and Apple Silicon compatibility.

The Spectral Phase Correction Module detects and dynamically corrects frequency-dependent phase shifts to achieve significantly improved spectral alignment and richer sound, while Auto-Align Post’s core algorithm has been further refined to deliver better overall results. The Spectral Correlation Meter [AAX] provides a detailed multi-band frequency correlation view.

Key features:

  • Microphones time-alignment of up to ±100ms (distances of up to ~112ft /34m.
  • 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.
  • Multi-channel support
  • Spectral Phase Correlation Meter.
  • Optimised for CPU efficiency and operation speed.
