Professional digital audio equipment may have a word clock input or output to synchronize timing between multiple devices.
Digital word clock code#
Time code can be used as an initial phase reference for jam sync using the word clock as the frequency reference. Timecode is metadata about the media data being transmitted. Word clock should not be confused with timecode word clock is used entirely to keep a perfectly timed and constant bitrate to avoid timing errors that can cause data transmission errors. The device which generates the word clock is the clock source for all the other audio devices. Various audio over Ethernet systems use communication protocols to distribute word clock. S/PDIF, AES/EBU, MADI, ADAT, and TDIF are some of the formats that use a word clock. Word clock is so named because it clocks each audio sample. In digital audio electronics, a word clock or wordclock (sometimes sample clock, which can have a broader meaning) is a clock signal used to synchronise other devices, such as digital audio tape machines and compact disc players, which interconnect via digital audio signals.
