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.
Once a 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 Bypass.
All parameters are displayed in a text box and have a resolution to 0.1 increments.
Parameters can be set by direct entry in the text box to replace existing text, then press
<Enter>, or <Tab>, 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 left or right arrow keys (the <Page Up>
and <Page Down> keys adjust in increments of 10 ms).
The table below lists each dynamics processor type, parameters, and factory default
settings for the processor.
