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).
