+<para>
+This audio filter (linearly) increases the difference between left and
+right channels (like the <application>XMMS</application> extrastereo
+plugin) which adds some sort of &quot;live&quot; effect to playback.
+This filter has one parameter:</para>
+
+<variablelist>
+<varlistentry>
+<term><option>mul</option></term>
+<listitem><para>
+is the difference coefficient, an optional floating point number that defaults
+to <literal>2.5</literal>. If you set it to <literal>0.0</literal>, you will
+have mono sound (average of both channels). If you set it to
+<literal>1.0</literal>, sound will be unchanged, if you set it to
+<literal>-1.0</literal>, left and right channels will be swapped.
