认识数字音频中的字时钟

Understanding the Wordclock of Digital Audio

数字音频设备必须在传输数字音频信号时同步,否则,数字音频信号可能不被正确地接收.可以通过一种叫做“字时钟”的方式来实现数字音频设备之间的同步:它实际上是在一个系统中为所有数字音频信号同步的时钟信号.本文揭示了该信号在同步过程中的工作原理和工作方式.

Digital audio equipment must be synchronized when digital audio signals are transferred from one device to another, otherwise, signals may not be received correctly and audible noise, glitches, or clicks may occur. Synchronization is achieved using what＇s called a wordclock, which is a clock signal for synchronizing all the digital audio signals in a system.
