AMR-WB+: a new audio coding standard for 3rd generation mobile audio servicesBroadcastes   (pdf)

Abstract:
Highly efficient low-rate audio coding methods are required for new compelling and commercially interesting applications of streaming, messaging and broadcasting services using audio media in 3rd generation mobile communication systems. After an audio codec selection phase 3GPP has standardized the extended AMR-WB (AMR-WB+) codec that provides unique performance at very low bit rates from below 10 kbps up to 24 kbps. This paper discusses the requirements imposed by mobile audio services and gives a technology overview of AMRWB+ as a codec matching these requirements while providing outstanding audio quality.
