Allowing Editing of Edit-Locked
Regions
If you attempt to edit an Edit-locked region,
Pro Tools warns you and prompts you to Cancel
or Allow the edit. If you allow an edit that keeps
any part of the region intact, the region remains
locked.
Muting/Unmuting Regions
Choosing the Mute/Unmute Region command
mutes playback of a selected region. Choosing
the command a second time unmutes the re-
gion. Regions that are muted become dimmed
to indicate their status.
To mute or unmute a region or regions:
1 With the Time Grabber, select the region or re-
gions you want to mute or unmute. The regions
can even reside on multiple tracks.
2 Choose Region > Mute/Unmute. When muted,
regions are dimmed.
Stripping Silence from
Regions
Strip Silence analyzes audio selections—across
multiple tracks—and removes (or extracts) any
areas of silence, dividing the selection into
smaller regions and removing the silent areas.
You can use Strip Silence to strip (remove) si-
lence from a region, or instead, extract the audio
and keep the silence. Getting rid of silent areas is
useful when preparing to compact audio (see
“Compacting an Audio File” on page 507). Strip
Silence automatically separates the selection
into separate regions, which is useful if you
want to quantize audio to musical values, or lo-
cate sound effects to SMPTE locations.
The Strip Silence Window
The Strip Silence window contains the following
controls that let you set the parameters by
which silence is defined when using Strip Si-
lence. Adjusting these controls causes rectangles
to temporarily appear in the selection (see
Figure 43 on page 734), indicating areas of si-
lence that will be affected by the Strip, Extract,
or Separate commands.
