This contribution presents the works recently completed or on-going in 3GPP and ITU-T on the development of new audio codecs. The main applications are wideband speech telephony, audio conferencing, and mobile multimedia applications including Packet-Switched Streaming (PSS), Multimedia Messaging (MMS) and Multimedia Broadcast/Multicast Service (MBMS). In the standardization process, tems-of-reference describing design constraints and performance requirements, test plans, selection rules are finalized first. Next, extensive subjective listening testing is conducted. The codec selection is based on the selection test results and the selection rules. Characterization phase of testing allows obtaining full amount of information on the codec behavior.
