Compressor
Square ONE Dynamics 23
Release
Adjusts the time the compressor takes to recover after the programme material falls back below threshold.
Both attack and release also respond to changes in programme level that remain over threshold. For
example, a signal that reduces in level but remains above threshold will still trigger a release. However, in
this case it will only be a partial release because the compressor is still required to generate gain reduction,
albeit for the new lower signal level.
Release time plays a very important role in compression. During periods of high signal level, gain is reduced.
When the signal level falls below the threshold, the gain will increase at a rate determined by the
RELEASE
control knob. If the release time is short, the gain will rise quickly. A long release time will mean that the
gain will stay at its reduced level, only recovering gradually, see Figure 11 “Compression fast and slow
release signal envelope graphs”.
Figure 11: Compression fast and slow release signal envelope graphs
The setting of the correct release time is a compromise. If is too short, background noise can cause effects
often known as 'breathing' and 'pumping'. A release time that is too long results in a signal that is not
compressed, but merely reduced in level. For effective compression the release time must be set as short as
possible before modulation of the background noise becomes too noticeable. The
ATTEN DEPTH gain
reduction meter will show how much actual compression is occurring. If it is steady, there is little active
compression, just a steady-state reduction in level. The faster the meter level moves up and down, the
harder the compressor is working.
