We have also introduced lossless data compression based on the source-coding theorem. In Chapters 16 and 17, we will address speech/audio and image/video coding. Lossy data compression is obtained by quantizing the analog signals, and the performance of quantization is characterized by the rate-distortion bound.

AUDIO AND WIDEBAND SPEECH COMPRESSION. Audio coding usually refers to the compression of high-fidelity audio signals, i.e., with 15- or 20-kHz bandwidth for consumer hi-fi, professional audio including motion picture and HDTV audio, and various multimedia systems. Sometimes the term audio coding is also used to refer to wideband speech coding, the compression of 7-kHz …

In early 2012 the ISO/IEC JTC1/SC29/WG11 (MPEG) finalized the new MPEG-D Unified Speech and Audio Coding standard, bringing together the previously separated worlds of general audio and speech coding. It does so by integrating elements from audio coding and speech coding into a unified system over a wide range of bit rates.
