This document defines the Opus interactive speech and audio codec.
Opus is designed to handle a wide range of interactive audio
applications, including Voice over IP, videoconferencing, in-game
chat, and even live, distributed music performances.  It scales from
low bitrate narrowband speech at 6 kbit/s to very high quality stereo
music at 510 kbit/s.  Opus uses both Linear Prediction (LP) and the
Modified Discrete Cosine Transform (MDCT) to achieve good compression
of both speech and music.  [STANDARDS-TRACK]

This document is a product of the Internet Wideband Audio Codec Working Group of the IETF.

This is now a Proposed Standard Protocol.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Internet
