| Abstract(in English) | This paper introduces standardization activities in ITU-T and ISO/IEC MPEG, comparing speech coding schemes based on time domain prediction and audio coding schemes based on frequency domain transform coding. ITU-T has standardized high compression telephone bandwidth speech coding schemes for two way communications and is extending to higher frequency bands and scalable coding to cover audio signals. In contrast, MPEG has standardized audio coding schemes for one way communications and is extending to multi-channel coding, lossless coding and low delay coding. 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. |
