Core AudioSuite Plug-Ins
The following basic plug-ins are installed automatically as part of the
Avid Media Composer system software installation:
• Invert — Inverts the polarity (phase of the audio file).
• Duplicate — Creates a new master clip from a selected audio clip.
The plug-in uses the IN and OUT points on the selected clip to
define the boundaries of the new clip.
• Normalize — Finds the peak value in the source audio file and
scales the entire file proportionally to that maximum value.
• Gain — Same as Normalize, but allows positive or negative gain
adjustment.
• Reverse — Rewrites the selected audio in reverse.
• DC Offset — Removes an audio artifact that is common in digital
audio files. A DC offset is caused by poorly calibrated
analog-to-digital converters (A/Ds), and can produce clicks and
pops on clip edit transitions if not removed.
• Time Compression/Expansion — Allows you to adjust the dura-
tion of a selected clip by creating a new master clip. This increases
or decreases the selection’s length without changing pitch.
• Pitch Shift — Changes pitch with or without changing length.
• EQ — Allows you to adjust frequency equalization on individual
audio clips.
• Compressor — Reduces the dynamic range of signals that exceed
a selected threshold by a specific amount.
• Limiter — Prevents signal peaks from exceeding a chosen level so
that they don’t overload amplifiers or recording devices.
• Gate — Reduces noise by decreasing the gain of signals that fall
below a user-selectable threshold.
• Expander/Gate — Performs the same function as the Gate plug-in
with the addition of expander features. Expanders are particularly
