Emerging end-to-end digital communication systems enable the use of full audio coding in a large and varied collection of applications for mobile environments. Applications include streaming services for music, news and sports as well as multimedia messaging services for person-to-person and business-to-person communications.

Now a breakthrough technology — Extended AMR Wideband (AMR-WB+) — addresses mixed speech and audio content at low bit rates. As an extension of the AMR-WB standard,
the AMR-WB+ audio codec combines advanced audio coding technology with unrivaled speech coding technology, allowing service providers to deliver consistent high-quality audio while making efficient use of their transmission capacity.

In addition to delivering rich, natural-sounding speech like AMR-WB, AMR-WB+ delivers
high-quality music, voice-over-music and voice-between-music, making it perfectly suited to
low-bit-rate mixed-content audio applications such as multimedia messaging; 3GPP
Packet-Switched Streaming (PSS), Multimedia Broadcast/Multimedia Service (MBMS) and IMS Messaging and Presence services; streaming audio over the internet; audio storage and playback; digital radio broadcasting; archiving and distribution of narrative content and
network-based language-learning applications.
