What is Clocking (Digital Audio)?

Clocking in digital audio refers to the timing system that controls when digital audio samples are captured, transmitted, or processed. It ensures that digital devices operate in precise synchronization when converting and transferring audio data.

Digital audio works by converting sound into a series of samples taken at regular intervals. The digital clock determines the exact timing of these samples. If multiple digital devices are connected—such as audio interfaces, converters, or digital mixers—they must share a common clock to stay synchronized.

Improper clocking between devices can cause problems such as clicks, pops, distortion, or unstable audio signals. To prevent these issues, one device in the system usually acts as the master clock, while the other devices synchronize to it as slave devices.
