Pro Tools 2024.6.0 supports using Auto-Align 2 as an ARA plugin.
Make sure you've installed the latest Auto-Align 2.2 (or newer) from the Downloads page to use AA2 ARA in Pro Tools.
Here's how:
1. Select all the tracks you'd like to align by clicking on the track's name in the Edit Window.
You can click on the first track, hold 'Shift', and click on the last one - all the tracks between will also be selected.
Hold 'Command' (mac) / 'Ctrl' (Windows) and click to add single tracks.
2. Hold 'Option' (mac) / 'Alt' (Windows) + 'Shift', click on the Elastic Audio Properties menu of any of the selected tracks, and select Auto-Align 2.
3. Click 'Align'.
4. You can use the master on/off switch to hear the before/after of all the aligned tracks.
