What’s New in Pro Tools 9.046
Configuring the Delay
Compensation Engine
The amount of Delay Compensation available
for your session is set in the Playback Engine.
Delay Compensation Engine
Pro Tools 9.0 supports Automatic Delay Com-
pensation for all Pro Tools systems. In lower ver-
sions of Pro Tools, only Pro Tools HD provided
Delay Compensation.
The Delay Compensation Engine setting deter-
mines how much DSP resources are dedicated to
Pro Tools Delay Compensation, which manages
DSP and host-based delays in the Pro Tools
mixer.
Within a session, you can choose to enable or
disable Delay Compensation (Options > Delay
Compensation).
To configure the Delay Compensation Engine:
1 Choose Setup > Playback Engine.
2 From the Delay Compensation Engine pop-up
menu, select Short, Long, or None.
3 Click OK.
Delay Compensation Settings
There are three settings in the Playback Engine
to dedicate processing resources for Delay Com-
pensation:
None Allocates no resources for Delay Compen-
sation.
Short Allocates minimum resources for Delay
Compensation for each channel. This is the
most efficient setting. For sessions with only a
few plug-ins that do not induce too much DSP
and host–based delay, this setting should be suf-
ficient.
Long Allocates maximum resources for Delay
Compensation for each mixer channel. For ses-
sions with a lot of plug-ins resulting in a large
amount of DSP and host–based delay, select this
setting.
Delay Compensation Time Mode
Delay values can be specified in either samples
or milliseconds, as selected with the Delay Com-
pensation Time Mode setting in the Operation
Preferences page.
