TCE Factor
The TCE Factor property displays the percentage
of change applied to the source file. On tick-
based tracks, this property is display only and
cannot be edited. On sample-based tracks, you
can change the TCE Factor to apply TCE to the
region. The percentage of the TCE factor is al-
ways calculated in relation to the source file.
Event Sensitivity
The Event Sensitivity property lets you filter
Event markers based on the analysis confidence
level. The confidence level for any detected
transient event is based, in part, on the clarity of
the transient. For example, if the file is a drum
loop, loud accented hits will be analyzed with a
higher degree of confidence than a soft, unac-
cented hit.
The Event Sensitivity acts like a threshold for
showing only the transient events that were de-
tected with a high degree of confidence. In
Warp or Analysis track views you will see the
number of Event markers decrease or increase as
you lower or raise the Event Sensitivity.
Lowering the event sensitivity can help reduce
the number of erroneously detected transients.
In turn, this can result in better sounding Elastic
Audio processing. Pro Tools preserves the de-
tected transients when applying TCE in order
avoid flamming and granulation of the tran-
sients. Consequently, false transients are also
preserved and the resulting sound quality can be
less than desirable. If you are working with au-
dio material that does not have clearly defined
transients, you may want to lower the Event
Sensitivity in the Elastic Properties, or you may
want to even edit the Event markers in Analysis
view.
Input Gain
It is possible to encounter clipping when time
compressing audio. Real-Time Elastic Audio
plug-ins provide a Clip indicator to let you
know when clipping has occurred. Rendered
Elastic Audio regions display a Clip indicator on
the region when clipping has occurred (see “Re-
gion Clip Indicator” on page 121).
If you encounter clipping when processing Elas-
tic Audio, use the Input Gain property to atten-
uate the gain of the audio signal before it is pro-
cessed.
For REX files, Pro Tools converts the slices
as Events with 100% confidence. Conse-
quently, setting the Event Sensitivity from
99% to 1% does not filter out any events
based on slices. However, if you set the
Event Sensitivity to 0%, all markers are fil-
tered out regardless.
