+::
+
+  $ mplayer -af volume=<v>:<sc> media.avi
+
+``<v>`` is the desired gain in dB for all channels in the stream from -200dB to
++60dB, where -200dB mutes the sound completely and +60dB equals a gain of 1000
+(default: 0).
+
+``<sc>`` Turns soft clipping on (1) or off (0). Soft-clipping can make the sound
+more smooth if very high volume levels are used. Enable this option if the
+dynamic range of the loudspeakers is very low.
+
+Maximizes the volume without distorting the sound::
