+@section atilt
+Apply spectral tilt filter to audio stream.
+
+This filter apply any spectral roll-off slope over any specified frequency band.
+
+The filter accepts the following options:
+
+@table @option
+@item freq
+Set central frequency of tilt in Hz. Default is 10000 Hz.
+
+@item slope
+Set slope direction of tilt. Default is 0. Allowed range is from -1 to 1.
+
+@item width
+Set width of tilt. Default is 1000. Allowed range is from 100 to 10000.
+
+@item order
+Set order of tilt filter.
+
+@item level
+Set input volume level. Allowed range is from 0 to 4.
+Defalt is 1.
