DYNAMICS | Compress
The compressor contains two modes depending on what
dynamic effect is desired. The compressor visualization
provides representation of the compressor curve and real-
time gain reduction amount.
Mode
The two modes for compressor are "Compress" and
"Comp/Limit". The "Compress" mode is a variable knee
compressor. The compressor is triggered by RMS levels
with automatic make-up gain. This makes it useful when
trying to get a smooth compressed sound. The
"Comp/Limit" mode is triggered by Peak levels with
traditional attack/release control.
Threshold / Ratio
These parameters operate like any standard compressor.
Threshold sets the input level at which compression will
occur. Ratio determines the amount of gain reduction at
which the threshold is triggered.
Make-up / Output Gain
When the mode is "Compress" the make-up gain is
automatic. However, an offset can be applied using the
Make-up Gain Parameter. When the mode is "Comp/Limit",
Output Gain can be added to the desired level.
Attack / Release
In both modes the Release Parameter determines the
speed at which the compressor stops reducing levels. In
"Comp/Limit" mode, the Attack Parameter determines the
speed at which the compressor starts reducing levels.
Because of the variable knee modes with "Compress",
there is no Attack Parameter.
Knee
In "Compress" mode there are two knee modes. In "Hard"
mode, the compressor ratio is used immediately when the
threshold is reached. In "Soft" mode, the compressor ratio
is gradually reached as the level increases past the
threshold. "Soft" mode is ideal for a smooth compressor
sound.
Insert Path
The compressor can be inserted "Pre EQ" or "Post EQ".
The "Pre EQ" value is useful for targeting compression on
specific frequency bands.
