Delay Compensation
Pro Tools 9.0 provides automatic Delay Com-
pensation for managing DSP and host-based de-
lays from plug-in inserts, and mixer routing
(bussing and sends). Lower versions of Pro Tools
only provided Automatic Delay Compensation
with Pro Tools HD.
With Delay Compensation enabled, Pro Tools
maintains phase coherent time alignment be-
tween tracks that have plug-ins with differing
DSP and host-based delays, tracks with different
mixing paths, tracks that are split off and recom-
bined within the mixer, and tracks with hard-
ware inserts.
To maintain phase coherent time alignment,
Delay Compensation should always be enabled
during playback and mixing. Delay Compensa-
tion should also be used in most recording situ-
ations.
Enabling Delay Compensation
To enable Delay Compensation:
 Select Options > Delay Compensation.
When Delay Compensation is enabled, the De-
lay Compensation status indicator in the Edit
Window Toolbar is displayed.
The Delay Compensation View for tracks can be
displayed in the Mix Window (see “Delay Com-
pensation View” on page 47).
For detailed information about using Delay
Compensation, see the Pro Tools Reference
Guide (Help > Pro Tools Reference Guide).
