2.1 Sound Radix Auto-Align Post

Dynamic time-alignment correction of moving location microphones

With Sound Radix Auto-Align Post, say goodbye to phase artifacts and comb-filtering caused by time differences between boom and lav microphones. With dynamic time-alignment correction, this essential tool removes the guesswork and gives you the crisp, precise audio you’ve been searching for. Get your hands on Auto-Align Post and take your audio-post production to the next level.

Since its debut in 2018, this powerful tool has taken the industry by storm, helping countless award-winning films and TV shows achieve outstanding dialogue. Why waste precious time on tedious editing when Auto-Align Post can do it in just a few clicks?

Auto-Align Post 2.1 takes an extensive step further by introducing a new spectral phase correction module, refined algorithm, and user interface. It brings native Apple silicon support for ARA2-VST3 in compatible DAWs and Adobe Premiere Pro extension compatibility. A new Adobe Premiere Pro extension is now included along with AAX for Pro Tools and universal ARA2-VST3 plugins for compatible DAWs such as Nuendo, Studio One, and others.

What’s 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.

Improved Algorithm

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

Spectral Correlation Meter [AAX]

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

ARA2 Compatibility

Long in the making, Auto-Align Post 2 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.
