A word clock or wordclock (sometimes sample clock, which can have a broader meaning) is a clock signal (not the actual device) used to synchronise other devices, such as digital audio tape machines and compact disc players, which interconnect via digital audio. S/PDIF, AES/EBU, ADAT, TDIF and other formats use a word clock. Various audio over Ethernet protocols use broadcast packets for the word clock. The device which maintains the word clock on a network is the master clock.

  • A word clock or wordclock (sometimes sample clock, which can have a broader meaning) is a clock signal (not the actual device) used to synchronise other devices, such as digital audio tape machines and compact disc players, which interconnect via digital audio. S/PDIF, AES/EBU, ADAT, TDIF and other formats use a word clock. Various audio over Ethernet protocols use broadcast packets for the word clock. The device which maintains the word clock on a network is the master clock. Word clock should not be confused with timecode; word clock is used entirely to keep a perfectly-timed and constant bitrate to avoid data errors. The word clock generator, usually built-in to analog-to-digital converters, creates digital pulses which contain no other data, and is considered essential to avoid frequency drift between the internal oscillators of each device. Timecode is actual data about the media content being transmitted, and is optional, being sent in a higher layer.
  • Wordclock ist ein Basistakt in der digitalen Audiotechnik, um Bearbeitungs- und Übertragungsvorgänge zwischen verschiedenen Audiokomponenten synchron zu halten. Der Wordclock hat genau die Periodendauer welcher von einem Abtastwert (Samplerate) eingenommen wird, unabhängig vom verwendeten Dynamikumfang. Mit Hilfe des Wordclock empfangen, senden und bearbeiten alle digitalen Geräte in der Kette die Datenströme synchron. Asynchronität bewirkt eine drastische Reduktion der Audioqualität und deutlich hörbare (unerwünschte) Effekte wie Pop- und Klick-Geräusche. Standardisierte Clock- bzw. Samplingfrequenzen: 44,1, 48, 88,2, 96, 192 (kHz). Die meisten Digitalformate übertragen Wordclock standardmäßig mit. (Im Gegensatz zu TDIF. ) siehe auch: Genlock, Homerecording
  • WordClock è un segnale di sincronia utilizzato nel campo audio professionale per sincronizzare fra loro gli oscillatori interni dei vari dispositivi audio digitali utilizzati (p. es. , registratori a nastro o lettori CD). Il WordClock consiste in un'onda quadra che ha frequenza pari alla frequenza di campionamento della periferica che abbia funzione di master; tutte le altre periferiche slave si adatteranno all'oscillazione del master tramite il segnale WordClock. Il WordClock viene distribuito alle varie periferiche audio digitali tramite cavi coassiali a 75Ω con connettore BNC.
