Delay Compensation Settings
There are three settings in the Playback Engine
dialog for dedicating DSP resources for Delay
Compensation:
None Allocates no DSP resources for Delay Com-
pensation.
Short Allocates minimal DSP resources of Delay
Compensation for each channel. This is the
most efficient setting for Pro Tools|HD Accel
systems.
Long Allocates maximum DSP resources of De-
lay Compensation for each mixer channel. Long
Delay Compensation uses the same DSP re-
sources used by high DSP overhead plug-ins.
To configure the Delay Compensation Engine:
Choose Setup > Playback Engine.
1
From the Delay Compensation Engine pop-up
2
menu, select a Delay Compensation setting.
Click OK.
3
The Delay Compensation status will be saved as
a session and system preference.
Delay Compensation View
The Delay Compensation View displays the to-
tal amount of plug-in delay on each track, lets
you apply a user offset of track delay, and dis-
plays the total amount of delay that Pro Tools
applies to each track. The Delay Compensation
View can be shown in the Mix Window.

To view Delay Compensation information:

sation.
Delay values can be specified in either samples
or milliseconds, as selected in the Display Pref-
erences page.
Plug-in Delay (dly) Indicator
The Plug-in Delay (dly) indicator shows the total
plug-in and hardware insert delay on the track.
This delay total is used by Pro Tools to calculate
the delay applied to other tracks to keep them
time-aligned. The track with the highest plug-in
and insert delay displays delay information in
orange.
Bypassing the track's reported delay to Pro Tools
can be useful if your total plug-in delay on a
track exceeds the amount allowed in the Delay
Compensation Engine setting. After bypassing
the track's reported delay, you must manually
nudge your track earlier by the reported amount
to achieve the proper Delay Compensation for
that track, while continuing to use Delay Com-
pensation (see "User Offset (+/–) Field" on
page 554.)
To bypass reporting plug-in delay to Pro Tools:
■
Control-click (Mac) the Plug-in Delay indicator.
The track delay will appear greyed out, and
Pro Tools will not use that track's plug-in delay
to calculate Delay Compensation for the other
tracks.
User Offset (+/–) Field
Plug-in
Delay indicator
This field lets you adjust track delays manually.
In addition to the automatic delay, positive or
User Offset
negative delay times can be entered in the user
