摘要
SACD是对现有CD的改进,它利用直接数字流(DSD)技术,和DST无损压缩方法,对数据进行存储。它可以存储2声道或6声道的声音数据。由于采用了全新的技术来记录声音,使它可以产生更好的声音质量,必将成为新一代的声音记录格式。本文详细介绍了1比特DSD编码技术的原理,和DST无损压缩方法的原理。
SACD is the improvement of CD in nowadays. It uses Direct Stream Digital (DSD) technology and Direct Stream Transfer (DST) lossless compression algorithm, to record audio data. It can store two channel or six channel audio data. Due to the use of a whole new technology to store the sound, it can reproduce the sound with better quality. So SACD must become a new recording format in the near future. This article introduces the principle of 1-bit DSD technology and the principle of DST lossless compression algorithm.
