+	  The Opus codec is designed for interactive speech and audio
+	  transmission over the Internet. It is designed by the IETF
+	  Codec Working Group and incorporates technology from Skype's
+	  SILK codec and Xiph.Org's CELT codec.
+
+	  It is intended to suit a wide range of interactive audio
+	  applications, including Voice over IP, videoconferencing,
+	  in-game chat, and even remote live music performances. It
+	  can scale from low bit-rate narrowband speech to very high
+	  quality stereo music.
