In any session, if you want to maintain absolute
time alignment across all tracks you should always compensate for signal processing delays.

Using Delay Compensation
Pro Tools provides automatic Delay Compensation for managing delays from plug-in and hardware inserts, and mixer routing (bussing and
sends). With Delay Compensation enabled,
Pro Tools maintains phase coherent time alignment between tracks that have plug-ins with differing DSP delays, tracks with different mixing
paths, tracks that are split off and recombined
within the mixer, and tracks with hardware inserts.
To maintain phase coherent time alignment,
Delay Compensation should always be enabled
during playback and mixing. Delay Compensation should also be used in most recording situations.
With HD OMNI, Delay Compensation is
not supported on Monitor output paths. Delay Compensation is only supported on
physical output paths (those not assigned
for the Monitor path).

Delay Factors
With Pro Tools, delay is incurred when you perform the following processes:
• Real-time processing with plug-in inserts.
• Mixing and routing with hardware I/O
(sends or inserts).
For information on the delay amounts for
plug-ins, refer to the Audio Plug-Ins Guide.
