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 <Enter>, <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 (<Page Up> and <Page Down> keys adjust in increments of 10 ms).
