It does not carry any absolute reference to a point in time: A clock is
used to keep a system's sample rate regular and accurate.

+ Word clock is usually at the frequency of the sample rate—at 48 kHz, its period is about 20 μs. Word Clock is the most
common sample rate based clock but other clocks do exist such as Black and
Burst, Tri-Level and DARS. Sample rates can be derived from these clocks as well.

Synchronization of multiple interfaces requires hardware support to sync
the clocks.
If two interfaces run at different clocks the only way to align the

expensive in terms of CPU usage and may decreases fidelity if done
incorrectly.
