    •  黑胶唱片的音质比CD或DVD好吗?

      Is the sound on vinyl records better than on CDs or DVDs?

      答案是模拟录制和数字录制是不同的。黑胶唱片是模拟录制,而CD和DVD是数字录制。让我们来看看下图。就本质而言,原声就是模拟信号。数字录制以一定频率(对于CD,每秒 44,100 次)抓取模拟信号的快照,并以一定精度来量化每次快照(CD是16位,这意味着其值必须是65,536个可能值之一)。阅读博闻网>>

      The answer lies in the difference between analog and digital recordings. A vinyl record is an analog recording, and CDs and DVDs are digital recordings. Take a look at the graph below. Original sound is analog by definition. A digital recording takes snapshots of the analog signal at a certain rate (for CDs it is 44,100 times per second) and measures each snapshot with a certain accuracy (for CDs it is 16-bit, which means the value must be one of 65,536 possible values).
