from, rather than switching on all at once. This changes the tonal
qualities of the compressed sound.
Expander
The Expander decreases the gain of signals that fall below a chosen
threshold. Expanders provide a gentler way of reducing noisy low-
level signals than the abrupt cut-off of a gate.
Ratio, Threshold, Attack, Release: These parameters have the
same meanings as in the Compressor (see above).
Range: This controls the maximum gain reduction (attenuation).
Hold: This determines how long the expander remains active after
the initial attack. Increasing this value is useful when, between
louder signals, there are small pauses or much quieter passages that
should not be amplified. In this use, the expander works like a noise
gate.
De-esser
This audio filter inconspicuously removes distracting sibilance from
recorded speech. The available parameters allow individualized fine
adjustment of the effect.
Frequency: This knob sets the frequency above which the De-esser
is deployed.
Range: This knob controls the maximum attenuation that will be
applied to the detected sibilance.

and Noise Reduction audio corrections.
