Lossless audio compression gradually becomes a focus of research on digital audio compression. 无损音频压缩(LAC)逐渐成为数字音频压缩领域的一个研究热点,很多研究机构和公司都提出了一些无损音频压缩(LAC)算法。
Lossless Audio Compression(LAC) based on Orthogonal Transform 基于正交变换的无损音频压缩(LAC)
This paper introduces an emerging ISO / IEC standard for lossless audio coding, MPEG-4 Audio Lossless Coding ( ALS ), and the comparison with other current state-of-the-art lossless audio compression algorithms was also provided. 介绍了MPEG-4的音频无损压缩标准草案&MPEG-4ALS,并且与目前常见的一些无损音频编码算法作比较。
Lossless audio compression technology is a technique that not only preserves the essence of the sound but also restores the precise bit information in that sound. 无损音频压缩(LAC)技术是一种既可保留音频信号原始音质,又可以准确无误地还原每一个比特音频信息的音频压缩技术。
A lot of research institutions and companies have proposed some lossless audio compression arithmetic. Because of its good performance in compression efficiency, complexity and flexibility, more attention are laid on MPEG-4 ALS ( MPEG - 4 Standard for Lossless Audio Coding ). MPEG-4ALS(MPEG-4StandardforLosslessAudioCoding)由于在压缩效率、复杂度、灵活性等方面都有不错的表现,受到了越来越多的关注。
