Dither (Audio Track Effect)
Dither is a dither-generation plug-in. The Dither plug-in minimizes quantization artifacts when
reducing the bit depth of an audio signal to 16-, 18-, or 20-bit resolution.
The following table lists the Dither plug-in parameters:
De-Esser panel
Frequency Sets the frequency band in which the De-Esser operates. Values range from 500 Hz
(lowest frequency) to 16 kHz (highest frequency).
When HF Only is disabled in the Options panel, gain is reduced in frequencies
within the specified range. When HF Only is enabled, the gain of frequencies above
the specified value will be reduced.
Set the Frequency control to remove sibilants (typically the 4–10 kHz range) and
not other parts of the signal. This helps prevent deessing from changing the original
character of the audio material in an undesired manner.
Range Defines the maximum amount of gain reduction possible when a signal is detected
at the frequency set by the Frequency control. Values range from –40 dB (maximum
de-essing) to 0 dB (no de-essing).
Set the Range control to a dB level low enough so that de-essing is triggered only
by sibilants. If the Range is set too high, a loud, non-sibilant section of audio
material could cause unwanted gain reduction or cause sibilants to be
over-attenuated.
To improve de-essing of material that has both very loud and very soft passages,
automate the Range control so that it is lower on soft sections.
