Automatic Delay Compensation
(Pro Tools|HD Systems Only)
On supported systems, the Delay Engine can be
enabled to have Pro Tools automatically com-
pensate for delays. For details on Automatic De-
lay Compensation requirements, operation, and
limitations, see the Pro Tools Reference Guide.
TimeAdjuster
(TDM Systems Only)
You can compensate for TDM plug-in-induced
delays by using the TimeAdjuster plug-in. This
plug-in lets you apply a specific number of sam-
ples of delay to the signal path of a Pro Tools
track. TimeAdjuster provides settings files that
apply the correct compensation time in samples
for delay introduced by one or more plug-ins.
See “TimeAdjuster” on page 55 for more infor-
mation about the TimeAdjuster plug-in.
Manual Delay Compensation
You can manually compensate for processing
delay by first calculating the amount of delay on
each track, and then nudging other track’s play-
lists later or earlier in time. This method is useful
when Automatic Delay Compensation is un-
available, or when you want to conserve DSP re-
sources.
Plug-Ins as Inserts
Real-time plug-ins are available as in-line inserts
on audio tracks, Auxiliary Inputs, and Master
Faders. A maximum of 5 real-time plug-ins can
be used per track.
When more than one insert is used on a track,
they process the audio in series, each effect be-
ing added to the previous one, from top to bot-
tom in the Mix window.
Inserts can be used in two ways:
On Single Tracks An insert can be applied to an
individual audio track or Auxiliary Input using
the Insert Selector on that track.
With in-line inserts, you control the level of ef-
fect by adjusting the controls of the plug-in.
As Shared Resources An insert can be used as a
shared resource in a send-and-return arrange-
ment by bussing signals from several tracks to
an Auxiliary Input, and applying the insert to
the Auxiliary Input track. With such an arrange-
ment, you can control the send level for each
track and the overall level of the effect can be
controlled from the Auxiliary Input track.
Shared arrangements let you make more effi-
cient use of your system’s processing power.
For information about TimeAdjuster in
Automatic Delay Compensation sessions,
see the Pro Tools Reference Guide.
If you are using both TDM and RTAS plug-
ins on the same track, RTAS plug-ins must
occur first in the signal chain, followed by
TDM plug-ins. You cannot place TDM
plug-ins before RTAS plug-ins.
On TDM systems, RTAS plug-ins can be in-
serted on audio tracks only. For Auxiliary
Inputs or Master Faders, use TDM plug-ins.
