+%description
+Libgdither is a GPL'd library library for performing audio dithering on PCM samples. The dithering
+process should be carried out before reducing the bit width of PCM audio data (eg. float to 16 bit
+int conversions) to preserve audio quality.
+
+It can do conversions between any combination of:
+
+in                              out (optionally interleaved)
+-------------------------------------------------------------
+normalised mono float           8bit unsigned ints
+normalised mono double          16bit signed ints

+                                normalised double
+
+At any bitdepth supported by the input and output formats.
