Sound Radix Auto Align Post 2.1

Soundradix AutoAlign Post 2 1

Sound Radix has released Auto Align Post 2.1 with Adobe Premiere Pro compatibility, streamlining the workflows for users of the popular video editing software application. Auto-Align Post has delivered outstanding-sounding dialogue in countless award-winning films and TV shows. It saved dialogue editors days of tedious work and has become an essential tool for many audio-post professionals.

Auto-Align Post enables dynamic time-alignment correction of moving location microphones, which 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.

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

Of the announcement, Sound Radix Founder Nir Averbuch said, "We're happy to empower Adobe Premiere Pro professionals with a native version of Auto-Align Post 2, saving the time needed for a roundtrip export to an external audio workstation. This continues our effort to help achieve rich, high-quality dialogue sound users have grown to expect from Sound Radix."

What’s New in Version 2.1

  • Adobe Premiere Pro compatibility
  • Native Apple silicon (M1/M2) compatibility
  • Improved algorithm

Highlights of Auto-Align Post 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 Spectral Phase Correction Module detects and dynamically corrects frequency-dependent phase shifts to achieve significantly improved spectral alignment and richer sound.
  • Improved Algorithm - Improved by iterations, Auto-Align Post’s core algorithm was further refined to deliver better overall results.
  • Spectral Correlation Meter [AAX] - Provides a detailed multi-band frequency correlation view.
  • ARA2 Compatibility - Auto-Align Post brings VST3 support for ARA2-compatible DAWs 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.
