Which term is commonly used as the main timing reference in a digital audio chain?

• A. Telecine
• B. Wordclock
• C. Main Clock
• D. Tri-Level Sync

Answer: (B)

In a digital audio chain, all devices must sample and process data in perfect lockstep. The timing reference that keeps everything aligned is the word clock. This dedicated clock signal is distributed to all digital devices (like interfaces, converters, and processors) so they can synchronize their sample timing to a single source. By sharing the same timing, the system avoids jitter and drift that would occur if each device used its own oscillator. Word clock is the established term for this synchronization signal in audio workstations and studios, making it the standard choice for a main timing reference. While terms like main clock or master clock can describe the general idea of a shared clock, word clock specifically denotes the practical clock line used to synchronize digital audio data across multiple devices. Telecine and Tri-Level Sync relate to film and video timing, not the primary timing reference used inside a digital audio chain.
