Chapter 20: Managing Regions
Managing the regions in a session lets you keep
system and storage requirements to a minimum,
and simplify archiving requirements. This chap-
ter describe several tools available to manage
files and regions in Pro Tools sessions.
Stripping Silence from
Regions
The Strip Silence command analyzes audio se-
lections—across multiple regions or multiple
tracks—and removes any areas of silence, divid-
ing the selection into smaller regions and re-
moving the silent areas.
You can use Strip Silence to automatically divide
a track into regions, which is useful if you want
to quantize audio to musical values, or locate
sound effects to SMPTE locations. It is also use-
ful if you want to get rid of silent areas to pre-
pare for compacting audio (see “Use this “power
delete mode” with caution, since deletion of
these files cannot be undone.” on page 313).
The Strip Silence Window
The Strip Silence window contains the following
four slider controls that allow you to set the pa-
rameters by which silence will be defined for this
operation. Adjusting these controls will cause
rectangles to appear in the selection (see
Figure 15 on page 308), indicating areas of si-
lence that will be removed.
Strip Threshold Sets the amplitude threshold
(from –48 dB to 0 dB) for Strip Silence. Audio
falling below this threshold is considered silence
and removed. Audio above the threshold is re-
tained and defined as new regions.
Minimum Strip Duration Sets the minimum dura-
tion (from 0 to 10,000 ms) that the material be-
low the threshold must last to be considered si-
lence.
Use this control to avoid countless small regions
that may occur within a selection.
Region Start Pad Specifies a time value to be
added to the beginning of each new region cre-
ated with Strip Silence. This is useful for preserv-
ing musical material that falls below the thresh-
old, such as the breath before a vocal phrase, or
the finger slide before a guitar chord.
Region End Pad Specifies a time value to be ap-
pended to the end of each new region created
with Strip Silence, thereby preserving the nu-
ances in the decay of the material.
