DC Offset Removal
The DC Offset Removal plug-in removes DC off-
set from audio files. DC offset is a type of audio
artifact (typically caused by miscalibrated ana-
log-to-digital convertors) that can cause pops
and clicks in edited material.
To check for DC offset, find a silent section in
the audio material. If DC offset is present, a
near-vertical fade-in with a constant or steady-
state offset from zero will appear in the wave-
form. Use the DC Offset Removal plug-in to re-
move it.
To remove DC offset from an audio clip:
1 Select the clip with DC offset.
2 Choose AudioSuite > Other > DC Offset Re-
moval
.
3 Ensure that Use In Playlist is enabled.
4 Click Render.
Duplicate
The Duplicate plug-in duplicates the selected
audio in place. Depending on how its controls
are configured, the new clip will appear in either
the Clip List or playlist. You can use this to flat-
ten or consolidate an entire track consisting of
multiple clips into one continuous audio file
that resides in the same place as the original in-
dividual clips.
The audio is unaffected by Pro Tools volume or
pan automation, or by any real-time plug-ins
that may be in use on the track as inserts. The
original audio file clips are merely rewritten in
place to a single duplicate file.
