Appendix A: DSP-Induced Delays in Mixing (TDM Only) 591
To use Delay Compensation to compensate for
DSP-induced delays:
1 Choose Setup > Playback Engine, and choose
a Delay Compensation setting (see “TimeAd-
juster and Delay Compensation” on page 591).
2 Choose Display > Mix Window Shows > Delay
Compensation View.
3 Choose Operations > Use Delay Compensa-
tion.
4 Use the track Delay Compensation displays
and other settings to do any of the following, as
needed:
• Define specific delay values for hardware
inserts
• Bypass Delay Compensation per track
• Fine tune Delay Compensation for each
track by entering a User Offset
TimeAdjuster and Delay
Compensation
TimeAdjuster plug-ins behave in a special way
when used with Delay Compensation.
• When Delay Compensation is enabled, all
other plug-ins (except TimeAdjuster) report
their delay to the Delay Manager, and this de-
lay is what is displayed in the Delay Indicator
view of each track. The Pro Tools 6.4 (and
higher) version of TimeAdjuster, however,
does not report its Delay setting to the Delay
Manager, preventing a type of “delay com-
pensation” loop from occurring.
• When Delay Compensation is turned off or
unavailable, TimeAdjuster operates as ex-
pected and applies its Delay to the track for
manual delay compensation.
This ability to maintain TimeAdjuster instances
and their Delay settings lets you more easily
transfer sessions between systems with and
without Delay Compensation.
Manually Compensating for
Delays
If you want to compensate for offsets incurred
by processing delays, there are different meth-
ods you can use:
• Apply sample-level delay to tracks with the
TimeAdjuster plug-in
• Physically adjust tracks in the Edit window
by the appropriate number of samples (for
example, by using the Nudge function).
• Use the same plug-ins on all tracks.
Using the TimeAdjuster Plug-In
You can use the TimeAdjuster TDM plug-in pro-
vided with your Pro Tools system to apply an
exact number of samples of delay to the signal
path of the tracks you are working with. Up to
2048 samples of delay are available.
Digidesign TDM plug-ins display their delay val-
ues in the track Channel Delay Indicators in the
Mix window. TimeAdjuster can be used to
match these delay values for tracks that need to
remain in phase (such as instruments recorded
with multiple microphones or stereo pairs).
To use TimeAdjuster to compensate for a time
delay:
1 In the Mix window, Control-click (Windows)
or Command-click (Macintosh) the track’s Vol-
ume Indicator to toggle between Volume
(“vol”), Peak (“pk”) and Channel Delay (“dly”)
indications. Delay values are shown in samples.
2 Apply the TimeAdjuster plug-in to a track
whose delay you want to increase (to match the
the first track).

sation” on page 591.
