Dynamics (DYN)
A dynamics processor alters the dynamic
range, the difference between the loudest
to the quietest portions, of an audio signal.
Each input channel provides two dynamics
processor blocks that, when inserted, provide
one of four types; AGC, Compressor, Limiter,
or a Noise Gate processor.
To insert a processor into an empty block,
select
Insert from the processor menu.
The menu appears when the block is
double-clicked, or is accessed from a context
menu that appears when the block is right-clicked.
Once the processor has been inserted, individual processor parameters can be changed
in the dialog box, accessed by double-clicking the processor block. For comparison, the
block can be bypassed by clicking a
Bypass button.
All parameters are displayed in a text box with a resolution of 0.1 (dB or ms). Parameters
are set by direct entry in the text box to replace existing text, then pressing ,
, or clicking to another area. Threshold, gain/attenuation, target, and ratio
parameters have adjustment points on the graph display. Use the mouse to
click +
drag the graph point to the desired destination or value. All time values have a horizontal
slider allowing adjustment in 1 ms increments by either a click + drag of the slider
handle, or focusing on the slider, then using or arrow keys (
and keys adjust in increments of 10 ms).
The table below lists factory default settings for each dynamics processor type and
parameter.
