“bite” of signal attacks while subsequently compressing the sustained portions of the
sound.
In general, both positive and negative values of this parameter are useful for applica-
tions where the normal envelope of a signal is being creatively manipulated to achieve
special effects.
Auto-Release
This parameter causes the effective Release time to be extended automatically based on
the dynamics of the input signal. This parameter emulates the program-dependent
release characteristics found on some classic analog compressor/limiters.
When not set “Off”, the Auto-release parameter treats the Release parameter value as a
minimum release time, extending it by as much as a factor of 10 depending on different,
selectable characteristics of the input signal:
In
Program-dependent mode,
release times are increased depending on how often,
how long and by how much the input signal (“program material”) exceeds the
Threshold. Release times increase slowly under sustained excursions of the input over
the Threshold, and typically return back to normal within a few seconds after the signal
level has fallen below it. This emulates the signal “memory effect” exhibited by some
electro-optical compressors.
In
Compression-dependent mode
, the release extension characteristics are similar, but
in addition depend on the amount of gain reduction being applied to the signal. Thus
the same signal will cause more release-time extension at higher compression Ratio
settings than at lower ones.
Uncompressed Waveform
Program-Dependent Release
Short Release
Longer Release
With Auto-release turned on, the release time becomes longer after an extended
period of compression.
