A staple for dialogue editing since its 2018 debut, Auto-Align Post stands out for correcting phase and comb-filtering between boom and lav mics without manual adjustments.
Sound Radix Auto-Align Post handles the time differences between boom and lav microphones that cause phase artifacts and comb-filtering. Its Adaptive Time Alignment automatically adjusts the timing of recorded microphones, letting dialogue editors and mixers align moving location mics after recording. Sound Radix first released it in 2018.
Auto-Align Post 2 adds ARA2 integration, improved algorithms, adaptive spectral phase correction, and a one-click re-align workflow. A real-time phase correlation meter and a track-focused edit window are part of the same release. Version 2.3 introduces native support for Blackmagic's DaVinci Resolve Studio.
The plugin offers a Dynamic mode for continuous phase and time correction on moving actors or cameras and a Static mode for stationary microphones, with the Spectral Phase Correction Module addressing phase-shift caused by electronic and acoustic filters. It supports AudioSuite, ARA2 on supported hosts, Adobe Premiere Pro, and DaVinci Resolve Studio, and includes multi-channel support.
Sound Radix Auto-Align Post is best for dialogue editors and mixers aligning boom and lav microphones on location recordings, including stationary setups in foley or music recording.
Sound Radix Auto-Align Post is completely free to download and use.
Auto-Align Post added native support for Blackmagic's DaVinci Resolve Studio in Version 2.3, integrating through the Blackmagic DaVinci Resolve Workflow Integration. Version 2.3.1 added compatibility with DaVinci Resolve Studio 20, along with improved handling of .mov and .mxf files and channel mapping. The plugin also works within Pro Tools, Cubase/Nuendo, REAPER, Studio One, and Adobe Premiere Pro through the supported formats, so dialogue editors and mixers can align boom and lav microphones inside their preferred environment. Check the developer's page for the current list of supported host versions.
Auto-Align Post runs on Mac and Windows. On Mac it needs a 64-bit Intel Core CPU or Apple Silicon chip, 8 GB of RAM or more, and macOS 10.9 or higher. On Windows it needs a 64-bit Intel Core or AMD CPU, 8 GB of RAM or more, and Windows 10 or higher. Both platforms require iLok License Manager 5.4 or newer. The plugin is described as highly optimized for CPU efficiency and operation speed. See the developer's page for full details.
Auto-Align Post is available as AudioSuite, ARA2 on supported hosts, an Adobe Premiere Pro extension, and Blackmagic DaVinci Resolve Workflow Integration. Its minimum supported hosts include Pro Tools 11 for AudioSuite and Pro Tools 2024.6 for ARA2 and AudioSuite, Cubase/Nuendo 11, REAPER 6.0, Studio One 4.6, and Premiere Pro 2020. This range lets dialogue editors and mixers align microphones within their preferred software. For the complete and current compatibility list, refer to the developer's page.

Auto-Align Post 2.3.3 is a bug-fix release focused on DaVinci Resolve. It improves audio file conversion to better preserve bit-depth, fixes a possible timeout when aligning, and improves support for auto-synced items including negative offsets, alongside additional stability improvements. Earlier 2.3.x updates added a user-customizable handles setting for ARA, an option to save aligned files to a custom folder in DaVinci and Premiere, and compatibility with DaVinci Resolve Studio 20. See the developer's changelog for the full history.
