Log Release
It is the time constants and especially the release pa-
rameter that decide if the processing of a compressor
is obvious or unobtrusive to the ear. As it is dicult to
achieve perfect results for all kinds of dierent material with
only one type of release curve, the xpressor 500 oers two dif-
ferent options to choose from: logarithmic and linear.
It is characteristic of a logarithmic release that the time con-
stant shortens when the amount of gain reduction increases.
The advantage of this behavior is that short and loud peaks
(e.g. drums) have a fast release time, while the remaining ma-
terial is processed with a slower release. Its smooth perfor-
mance makes the Log Release especially useful for mastering
and stereo buss compression.
The linear mode, however, has a straight release prole,
without the slower tapering release characteristic of the Log
mode. The linear mode is a good choice for more aggressive
dynamics control of dry signals, and it is especially useful
when you want to process signals which do not have a long
decay period.
