Latency in telephone calls is sometimes referred to as mouth-to-ear delay the telecommunications industry also uses the term quality of experience (QoE).
In all systems, latency can be said to consist of three elements: codec delay, playout delay and network delay. Low latency audio in computers is important for interactivity. Excessive audio latency has the potential to degrade call quality in telecommunications applications. Latency can be a critical performance metric in professional audio including sound reinforcement systems, foldback systems (especially those using in-ear monitors) live radio and television.
Potential contributors to latency in an audio system include analog-to-digital conversion, buffering, digital signal processing, transmission time, digital-to-analog conversion and the speed of sound in the transmission medium. Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters a system and when it emerges.
