Auto Time Adjuster (ATA) is an RTAS plug-in for Pro Tools LE/M-Powered, designed to ease your workflow when using plug-ins that generate significant latency. Currently to compensate for plug-in latency you have to either move individual audio tracks backwards/forwards, or use the included Time Adjuster plug-in to fix the delay of each track in turn. One plug-in change can mean a lot of tweaks every time you change a plug-in in a large project.
Auto Time Adjuster uses audio pinging to automatically calculate and compensate for insert latency on your audio and aux tracks with the click of a button. When you add or remove a plug-in on a track all you need to do is click the ping button on the master ATA to calculate all current latency and synchronise your tracks, even when using hardware inserts.
As ATA measures the actual latency of each track in your mix it provides the tightest timing possible, native ADC relies on values reported by the plug-ins themselves, and they don't always report the actual delay they are adding to your tracks.
