Auto-Align Post 2 keeps location microphones such as boom and lavalier mics in phase, adapting its time alignment as actors and cameras move.

It corrects up to ±100 ms of offset with adaptive spectral phase correction, and costs $399.

Best for: Vocals. Genres: Ambient & Cinematic.

What it does

Auto-Align Post 2 is "the fast & simple way to get location mics in phase". It is a separate product from Auto-Align 2, built for dialogue: it time-aligns and phase-corrects boom and lavalier mics even when the distance between them changes during a take.

Dynamic mode: adaptive time alignment that keeps adjusting as actors and mics move.
Static mode: a fixed time and spectral phase correction for mics that stay in place.
Adaptive Spectral Phase Optimization: corrects frequency-dependent phase shifts, such as those caused by filters in wireless systems, to remove comb filtering between boom and lav.
Wide range: aligns offsets up to ±100 ms, about 34 meters.
Metering: a spectral phase correlation meter shows how well the channels match.
Offline processing: it renders via ARA2 or AudioSuite rather than as a real-time insert, and Sound On Sound found it quick even on 20-minute files.
Multi-channel: handles more than two mics, with CPU-optimized processing.

Version 2.3.3 (January 2026) works as AudioSuite in Pro Tools, through ARA2 in supporting DAWs, and natively in DaVinci Resolve Studio and Adobe Premiere. It has a trial.

When to use it

Auto-Align Post 2 is the pick for dialogue editors and post mixers whose boom and lav mics change distance throughout a take. Compared with Auto-Align 2, it adds a dynamic mode that keeps re-aligning as people move, works inside Resolve and Premiere, and covers a wider offset range, but it costs twice as much and runs offline rather than live. Compared with manual tools such as Waves InPhase or Eventide Precision Time Align, it removes the sample-by-sample nudging that moving mics would need. For music sessions where the mics stay put, it is more than you need.

Best for: film, TV and podcast dialogue recorded with boom plus lavalier mics, and location recordings with several moving mics.
Genres: post-production work rather than music.
Look elsewhere if: you only align static music mics or want real-time processing; Auto-Align 2 costs half as much.
Tip: use the lavalier as the reference track, since its position relative to the actor stays most consistent (Pluginerds).

What producers say

Reviewers see it as a real time-saver for professional dialogue work, with the price as the main hurdle.

Sound On Sound (Matt Houghton, 2022) said it "just works" with minimal input and saves a lot of time on film projects, recommending it for commercial post facilities.
Pluginerds praised the dynamic mode and spectral phase correction, saying it turns days of manual nudging into a few clicks.
Criticisms: the price, and processing time that grows with file length (Sound On Sound).
