Technologies for speech and audio coding
Takehiro Moriya · 2009
This paper reviews some important technologies for speech and audio coding, contrasting time domain and frequency domain processing. These technologies have contributed to the standardization activities in ITU-T and ISO/IEC MPEG, respectively. It is interesting that the standardization targets for speech and audio have started to converge recently. The MPEG USAC (Unified Speech and Audio Coding) scheme, which is being actively developed, may make use of most of the important technologies for speech and audio that have been developed so far.
