DC Offset Removal (AudioSuite)
The DC Offset Removal plug-in removes DC offset from your audio files. DC offset describes a
specific type of audio artifact that might appear in digital audio signals.
You can identify DC Offset in a waveform because it appears as a near-vertical fade-in with a
constant or “steady-state” offset from zero when the file is actually “silent” (it contains no
audible audio). The DC Offset plug-in can help remove (or at least reduce) the DC offset from
your source audio files.
DeEsser III — Dynamics III (RTAS and AudioSuite)
The DeEsser III plug-in reduces sibilants and other high frequency noises that can occur in
vocals, voiceovers, and wind instruments such as flutes. These sounds can cause peaks in an
audio signal and lead to distortion.
The De-Esser reduces these unwanted sounds using fast-acting compression. A Threshold
control sets the level above which compression starts, and a Frequency control sets the frequency
band in which the De-Esser operates.
To use de-essing most effectively, insert the De-Esser after compressor or limiter plug-ins.
n
The De-Esser has no control to directly adjust the threshold level (the level that an input signal
must exceed to trigger de-essing). The amount of de-essing will vary with the input signal.
The following table lists the DeEsser III plug-in parameters:
Decay Controls the rate at which the reverberation decays after the original direct signal stops. The
value of the Decay parameter is affected by the Size and Algorithm parameters. You can set this
parameter to infinity on most algorithms for infinite reverberation times.
Pre-Delay Lets you determine the amount of time that elapses between the original audio event and the
onset of reverberation.
HF (High
Frequency)
Cut
Controls the decay characteristic of the high frequency components of the reverberation. It acts
in conjunction with the LP Filter control to create the overall high frequency contour of the
reverberation.
LP Filter Controls the overall high frequency content of the reverberation by allowing you to set the
frequency above which a 6-dB-per-octave filter attenuates the processed signal.
