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