What is Jitter (Audio)?

Jitter in digital audio refers to small timing errors in the clock signal that controls when digital audio samples are processed or transmitted. These timing variations can affect the accuracy of digital audio conversion and playback.

In a digital audio system, samples must be captured and processed at extremely precise time intervals. If the clock timing fluctuates slightly, the spacing between samples becomes inconsistent. This timing instability is known as jitter.

Excessive jitter can lead to subtle audio problems such as distortion, reduced clarity, or a loss of detail in the sound. High-quality digital audio systems use stable clock sources and proper synchronization between devices to minimize jitter and maintain accurate audio reproduction.
