Audio Compression (MPEG-Audio and Dolby AC-3)

  • Bill Buchanan


CD-quality stereo audio requires a bit rate of 1.411200 Mbps (2 x 16 bits x 44.1 kHz). A single-speed CD-ROM can only transfer at a rate of 1.5 Mbps and this rate must include both audio and video. Thus, there is a great need for compression of both the video and audio data. The need to compress high-quality audio is also an increasing need as consumers expect higher-quality sound from TV systems and the increasing usage of digital audio radio.
