Chapter 18: Advanced Editing 257
Pre-Roll
Specifies a time value to add to the
start of regions created with the Strip Si-
lence command. For example, a value of
200 ms of Pre-Roll will add 200 ms to the
beginning of each stripped region. Differ-
ent values here can be useful for preserving
certain types of data, such as breaths on vo-
cal tracks that would otherwise be stripped
out, resulting in an unnatural, “gated”
sound.
Post-Roll The value that you enter here is
appended to the end of regions created
with the Strip Silence command.
Region Naming
The Strip Silence dialog also contains pa-
rameters for how resulting regions are
named. You can choose to use standard
naming conventions, or define your own.
The Custom naming option has four pa-
rameters:
Name Specifies the base name for regions
created with the Strip Silence command.
Auto Number Start Specifies the number at
which sequential auto-numbering starts.
Leading Zeros Specifies the number of ze-
roes that occur before the appended auto
numbers.
Suffix Specifies any text appended to the
end of the name, following the auto num-
bering.
For example, if you set the naming param-
eters to:
• Name = SFX
• Auto Number Start = 23
• Leading Zeros = 1
• Suffix = .Reel1
The names generated for regions created by
the Strip Silence command would be:
• SFX023.Reel1
• SFX024.Reel1
• SFX025.Reel1
• SFX026.Reel1
• SFX027.Reel1
• SFX028.Reel1
To identify silence:
1 Select a portion of silence in a track.
2 Choose Edit > Identify Silence. A dialog
appears displaying the silence’s dB parame-
ters. If these are satisfactory, click OK.
To strip silence from a selection:
1 Select one or more audio regions.
2 Choose Edit > Strip Silence.
3 Enter the desired parameters to define
the silence. If you had previously identified
silence, these parameters are filled in with
the pre-calculated values.
4 Choose a naming scheme. If you choose
Custom, enter the desired parameters.
5 Click OK. Pro Tools divides the selection
into regions, stripping out any areas that
meet your specifications for silence.
