The filter accepts the following options:
@table @option
-@item duration, d
-Set silence duration until notification (default is 2 seconds).
-
@item noise, n
Set noise tolerance. Can be specified in dB (in case "dB" is appended to the
specified value) or amplitude ratio. Default is -60dB, or 0.001.
+
+@item duration, d
+Set silence duration until notification (default is 2 seconds).
+
+@item mono, m
+Process each channel separately, instead of combined. By default is disabled.
@end table
