Auto dehiss: Reducing broadband noise
Process Mode
Auto dehiss offers four combinations of processing modes:
■
Noise detection mode may be either Auto or Manual
In auto mode, the Duo processor automatically determines the noise level contained within the
signal, whereas in manual mode the noise level is set by the user.
■
Channel mode may be either Left/Right or Mid & Side
Left/Right mode processes the left and right channels of a stereo signal in the conventional
manner. Mid & Side mode surrounds the process in a mid/side encoder and decoder. This
allows you to process the signal in Mid & Side format whilst retaining conventional Left/Right
stereo at the input and output.
