To compensate for delay that exceeds the
compensation limit, do one of the following:
„
If the Delay Compensation Engine setting in
the Playback Engine is set to
Short
, change the
setting to
Long
.
– or –
„
If the Delay Compensation Engine is already
set to
Long
, do the following:
• Bypass the reported delay for the track by
Start-Control-clicking (Windows) or Com-
mand-Control-clicking (Mac) the Delay in-
dicator. The track information is grayed out
once it is bypassed.
– and –
• Manually nudge any audio data on the
track earlier by the amount of delay re-
ported in the track’s Delay indicator.
Low Latency Monitoring During
Recording
When an audio track is armed for recording
(record-enabled), TrackInput-enabled, Destruc-
tivePunch-enabled, or punched in, the track’s
Delay Compensation is automatically sus-
pended (and the Track Compensation indicator
displays 0). This provides low-latency monitor-
ing on those track outputs.
Tracks that are not record enabled still apply De-
lay Compensation. Pro Tools automatically
compensates for any timing discrepancies be-
tween the recorded material and the delay-com-
pensated mix. When the track is played back
(with both record-enable and TrackInput dis-
abled) it is correctly time-aligned with the other
delay-compensated tracks.
Overriding Suspended Delay Compensation
You can override the automatic suspension of
Delay Compensation on record-enabled tracks,
but you may introduce latency in the signal
path by the amount of Delay Compensation.
This latency may be acceptable depending on
the recording source.
To apply Delay Compensation to tracks where
Delay Compensation was suspended:
„
Start-Control-click (Windows) or Command-
Control-click (Mac) the Track Compensation in-
dicator. Track delay is applied to the track and
the Track Compensation indicator displays in
blue.
Delay Compensation on Auxiliary
Inputs
Delay Compensation on Auxiliary Inputs can be
bypassed to let you monitor outside sources
(such as the audio tracks of a slaved video deck)
with minimal latency, while still reporting the
track’s delay.
To bypass an Auxiliary Input’s Delay
Compensation:
„
Start-Control-click (Windows) or Command-
Control-click (Mac) the Track Compensation in-
dicator. The reported track delay will be zero,
and will appear grayed out.
In certain dubbing workflows you may want
to cascade bus recordings to multiple tracks.
In these cases you should be sure to override
the automatic suspension of Delay Com-
pensation on the recording tracks.
