CODECPRO AMR-WB+ (EXTENDED AMR-WB) CODEC
3GPP SPEECH AND AUDIO STANDARD CODEC

The AMR-WB+ speech and audio codec is the 3GPP-recommended hi-fi audio codec for MMS, PSS and MBMS services over GSM and WCDMA networks. AMR-WB+ is also recommended for DVB-H applications. AMR-WB+ scales to cover the full audio spectrum and uses high-efficiency parametric stereo (HE-PS) to maintain high-fidelity stereo image reproduction at even the lowest bit rates and excellent quality at higher rates. Coded AMR-WB+ media can be encapsulated in 3GPP (.3gp, i.e., MMS) or MPEG-4 (.mp4) file formats and used along the entire delivery chain in multimedia applications. The RTP payload format for AMR-WB+, defined by the IETF, supports interleaving for robust streaming and forward error correction (FEC) for enhanced robustness.
