Compressor
Threshold
0.0 to -60.0dB.
Controls the level below which compression
starts to take place.
Ratio
1:1 to 20:1
Ratio determines the amount of compression to
be used. A ratio of 1:1 provides no compression,
whereas approaching 20:1 corresponds to a
limiter.
Knee
Hard / Soft
A soft knee provides a more gentle transition
between the signal below threshold to that above.
In general, it provides the least obtrusive gain
control and is often the preferred setting for
finished mixes, with a Hard Knee considered
more successful in creative applications.
The compressor combines aspects of both the traditional ratio style compressor and the soft-knee approach,
making it equally adept at creative work and unobtrusive level control. Many advanced facilities that enable
quick setup, predictable results and a musical analogue style response, have been incorporated including:
•
Wide Threshold range for accurate compression;
•
Automatic programme dependant Attack and Release for trouble free setup;
•
Adjustable Ratio from very gentle compression through to absolute Limiting;
•
Soft/Hard knee for creative work or unobtrusive level control.
•
Useful LED type bar meters showing gain reduction.
•
The compressor can be bypassed to use the plug-in as a limiter only.
Traditionally, soft-knee compressors have been preferable for unobtrusive level control where the original
sound is to be changed as little as possible, with ratio type compressors more successful in creative applications
or where large amounts of gain reduction are required. By combining these two elements, the Compressor
Plug-In is capable of outstanding results in a very wide range of sound situations.
Attack
100uS to 100mS.
Controls the speed that the compressor responds
to signals that exceed the level set by threshold.
Release
50.0mS to 2.0S.
Sets the time taken for the signal to return to
normal after the input level has fallen below
threshold. Be careful, with very long release
settings, the Compressor might never have
enough time for a total recovery between the
signal peaks. With very short release settings,
low frequency signals will have a tendency to
distort as the Compressor tries to release on
the signal sinewave.
Auto
When selected, Auto disables the Attack and
Release controls and continually optimises the
attack and release times to suit the dynamics
of the material being processed. In general, this
setting will produce the least obtrusive level
control on signals with widely varying dynamics
or complete mixes.
