ExpressFX Dynamics

The Dynamics effect allows you to precisely tailor the gain of a signal. Sound engineers can create dramatic to subtle compression and expansion without sacrificing total control at all levels.

1. Open the ExpressFX Dynamics dialog.

2. Choose a preset from the Name drop-down list, or adjust the controls as desired:

   1. Drag the Threshold fader to set the level at which the dynamics processor begins acting on the signal.

   2. Drag the Ratio slider to set the compression ratio of input to output levels.

      IMPORTANT

      Excessive compression starting at a low threshold will usually produce distortion.

   3. Drag the Attack slider to set the time required for the dynamics processor to start acting on the signal once the level rises above the threshold.

      A low Attack time preserves percussive attacks. Higher values cause sounds to slowly swell up in volume.

   4. Drag the Release slider to set the time it takes the gain of the dynamics processor to change from one to zero once the level falls below the threshold.

      A long Release time preserves natural-sounding decays; otherwise long decays will be cut off.

3. Select the Auto gain compensate check box to apply gain during processing to keep the maximum input and output levels constant. In general, this gain will be equal to the decibel level of the highest envelope point in the graph.
