【 摘 要 】

Audio compression has become one of the basic technologies of the multimediaage. The change in the telecommunication infrastructure, in recent years, fromcircuit switched to packet switched systems has also reflected on the way thatspeech and audio signals are carried in present systems. In many applications,such as the design of multimedia workstations and high quality audiotransmission and storage, the goal is to achieve transparent coding of audio andspeech signals at the lowest possible data rates. In other words, bandwidth costmoney, therefore, the transmission and storage of information becomes costly.However, if we can use less data, both transmission and storage becomecheaper. Further reduction in bit rate is an attractive proposition in applicationslike remote broadcast lines, studio links, satellite transmission of high qualityaudio and voice over internet.
