REACTION ENVELOPE Section
The ATTACK, HOLD and RELEASE controls together define the shape of the gain
reduction envelope created when a transient breaches the threshold.
ATTACK Touch
Pad
This defines how quickly the gain reduction can kick in. While fast attack times often
seem to be the best idea, slower attack times can sound more musical and natural.
In general, for de-essing, fast attack times are required — as fast as possible
without distortion. When working with low frequency sounds, however, you may
want slower attack times.
HOLD Touch
Pad
This defines how long the gain reduction holds its level before it is allowed to decay
away. Generally speaking this needs to be as small as possible for de-essing work.
RELEASE Touch
Pad
This defines how quickly the gain reduction can decay back to normal after the
trigger that caused the onset of gain reduction has disappeared. Generally speaking,
this needs to be more than the minimum setting to avoid distortion. With the attack
and release too fast (especially the release), the gain envelope fits around the
waveform itself, rather than fitting the general level envelope of the signal, so
causing distortion.
