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 difficult to 

achieve perfect results for all kinds of different material with 

only one type of release curve, the xpressor 500 offers two dif-

ferent options to chose 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  profile, 

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.
