http://www.voiceage.com/USAC.html
USAC (Unified speech and audio coding) is an MPEG codec speech and audio codec defined in ISO/IEC 23003-3. USAC also defines a profile known as the Extended High-Efficiency AAC (xHE-AAC) audio codec which is the latest member of the MPEG AAC codec family. In order to achieve equally good quality for coding audio and speech, USAC employs the proven MDCT (modified …

Unified speech and audio coding (USAC) is one of the latest coding technologies. It is based on a switchable coding structure, and has demonstrated the highest levels of performance for both speech and music contents. In this paper, we propose an extended version of USAC with a single-mode of operation—which does not require a

ISO/IEC MPEG USAC Unified Speech and Audio Coding 1. Introduction Traditionally, speech and audio sig-nals have been encoded using different coding schemes because of their differ-ent applications. Regarding speech, speech coding schemes that encode nar-row band signals (up to 3.5 kHz) at lower bitrates have been used for tele-phony applications. In the case of music, …
