Chapter 20: Managing Regions 309
7 Once the Strip Silence rectangles encompass
the audio that you want to keep, press the Strip
button.
The material defined as silence is removed from
the selection and new regions are created, which
also appear in the Audio Regions List.
The Strip Silence command is nondestructive
and does not remove audio data from parent au-
dio files. In addition to the Undo command,
you can use the Heal Separation command to re-
store stripped material.
Inserting Silence
The Insert Silence command is a simple and
convenient way to insert silence in sessions.
This command allows you to make a selection
on a track (or tracks) and insert precisely that
amount of silence. In Shuffle mode, all data on
the track is shuffled later in the track by an
amount equal to the selection.
In Grid mode, the Insert Silence command
works just like the Clear command.
Shuffle Mode When inserting silence on multi-
ple tracks in Shuffle mode, the following condi-
tions apply:
◆ If any track is displayed as audio or MIDI data,
the selected duration of silence is inserted into
the audio or MIDI data and all underlying auto-
mation data on all selected tracks. All subse-
quent regions are shuffled by the amount of
silence inserted. On MIDI tracks, only notes that
are selected from the beginning are affected, so
if you have selected the tail of a note and you In-
sert Silence, the note will remain unchanged.
◆ If all selected tracks are displayed as automa-
tion data, the selected range is cleared of auto-
mation data only of the type visible on each
track. Regions are not shuffled. Instead, a blank
gap appears equal to the length of the selection.
◆ If all selected tracks are displayed as automa-
tion data, press the Start key (Windows) or Con-
trol (Macintosh) while choosing the Insert
Silence command to inserts silence on all auto-
mation playlists for all selected tracks. Regions
are not shuffled.
Slip Mode When inserting silence on multiple
tracks in Slip mode, the following conditions
apply:
◆ If any track is displayed as audio or MIDI data,
the selected range is cleared of audio or MIDI
data and all underlying automation data on all
selected tracks.
◆ If all selected tracks are displayed as automa-
tion data, silence is inserted only into the auto-
mation type visible on each track.
◆ If all selected tracks are displayed as automa-
tion data, press the Start key (Windows) or Con-
trol (Macintosh) while choosing the Insert
Silence command to insert silence on all auto-
mation playlists for all selected tracks.
To insert silence into a track:
1 Make a selection in a track or tracks. The
length of the selection determines the duration
of the silence inserted.
2 Choose Edit > Insert Silence.
For Shuffle mode, Pro Tools inserts the selected
amount of silence. In the process, it splits the re-
gions at the beginning of the insertion point,
and moves the new regions later in the track by
an amount equal to the length of the selection.
Strip Silence works with stereo and multi-
channel tracks, and keeps their audio re-
gions phase-coherent.
