摘要

自1988年以来，ISO/IEC JTCI/SC29 WG11 (MPEG)一直致力于视频和音频信号的标准化。MPEG的音频小组正在研究用于高质量数字音频的比特率降低系统。由于该标准化工作的第一阶段已经完成，MPEG/Audio正在将其工作扩展到多通道音频编码系统以及低采样频率和低比特率的中质量编码。未来的标准化工作旨在下一代编码器适合高质量的音频传输和存储，比特率为每通道64 kb/s或远低于64 kb/s。

Current and future standardization of high-quality digital audio coding in MPEG

Since 1988 ISO/IEC JTCI/SC29 WG11 (MPEG) is working on the standardization of video and audio signals. The Audio subgroup of MPEG is working on bit rate reduction systems for high quality digital audio. Since the first phase of this standardization effort has been finished, MPEG/Audio is extending its work to multichannel audio coding systems as well as to medium quality coding at lower sampling frequencies and lower bit rates. Future standardization work aims at next-generation coder suitable for high quality audio transmission and storage at bit rates of 64 kb/s per channel and well below.<>
