The release parameter, on the other hand, has
a strong influence on the character of the compression
being obvious or unobtrusive to the
ear. As a general rule, linear or logarithmic release
curves will be employed if a discreet performance
of the compressor is required.
It is characteristic of a logarithmic release that
the time constant shortens when the gain reduction
raises. The advantage of this is that
short and loud peaks (e.g. drums) have a fast
release time, while the remaining material is
processed with a slower release time.
But if intentionally striking and creative compression
as well as producing new and interesting
sounds are the sought-after goals, it
definitely makes sense to turn the established
approach upside down. For this reason, you can
switch the release curve of the mpressor from
linear to antilogarithmic.
Compared to a logarithmic release curve, the effect
of the Anti Log option behaves just the other
way round: If the threshold point is passed,
the release time will no longer be shortened at
first. If the input signal starts to decline, however,
the release time will become faster.
