回答: 谁给我讲讲CD 的音质和数码音乐的差别？由 tom_cat 于 2008-01-23, 14:54:44:

CD is a compressless digital format. its size is exact 16bitx2chxtime on a disk.
Lossless format is just a copy of CD contents + compress. there are a few popular, Microsoft, Apple and FLAC.
MP3, check it yourself. http://en.wikipedia.org/wiki/MP3

- 所以CD也不是立体声？我看过一个科教片里说立体声必须要5个声道。 (无内容) - tom_cat (0 bytes) 2008-01-23, 16:19:54 (199644)
  - 2-channel is 立体声 or stereo. 5 is surrounding - 社精办 (48 bytes) 2008-01-23, 16:25:05 (199650)
