ATA Auto Time Adjuster: Delay Compensation Plugin by Mellowmuse Free Download

ATA is inserted on each track in the mix. The latency of every plugin and outboard insert is then measured using a short burst of audio, called a ping, triggered from the ATA on the master fader.

Based on those measurements, ATA calculates and sets the appropriate delay on each ATA on each track or bus. Mellowmuse says this brings all tracks into alignment and provides the tightest timing possible.

Because the latency is measured directly, the result does not depend on what each plugin reports about itself. That also covers outboard gear connected through hardware inserts.

Individual ATAs can be locked, so their delay settings stay fixed when you re-measure the rest of the session. Latency can also be entered manually when you already know the value.

The group delay preview in the Pro Tools mixer lets you check the compensation across the session before committing to it.

The latency limit is 50,000 samples, which leaves room for high-latency chains and large sessions.
