+ This option affects the fade, snooze and sleep subcommands. It is
+ ignored in set mode.
+
+ The argument must be a number between 0 and 100. The default value
+ 0 corresponds to linear scaling. That is, the value of the mixer
+ channel is increased or decreased in fixed time intervals until the
+ destination value is reached. Exponents between 1 and 99 cause low
+ channel values to be increased more quickly than high channel values.
+ Large exponents cause greater differences. The special value 100 sets
+ the destination value immediately. The command then sleeps for the
+ configured fade time.
