Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters a system, and when it emerges.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, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.
Network latency (link offset) is the time difference between the moment an audio stream enters the source (ingress time), marked by RTP timestamp in the media packet, and the moment it leaves the destination (egress time). Latency depends on packet time, propagation and queuing delays, packet processing overhead, and buffering in the ...
Low latency is important for many users of audio over Ethernet technologies. [6] [note 2] EtherSound can deliver up to 64 channels of 48 kHz, 24-bit PCM audio data with a network latency of 125 microseconds. [2] If A/D and D/A conversions are included, this latency is about 1.5 milliseconds, the major part of this latency being caused by the ...
CobraNet is a combination of software, hardware, and network protocols designed to deliver uncompressed, multi-channel, low-latency digital audio over a standard Ethernet network. Developed in the 1990s, CobraNet is widely regarded as the first commercially successful audio-over-Ethernet implementation.
Audio Video Bridging (AVB) is a common name for a set of technical standards that provide improved synchronization, low latency, and reliability for switched Ethernet networks. [3]
The worst-case latency requirement is defined as 2 ms for Class A and 50 ms for Class B, but has been shown to be unreliable. [5] [6] The per-port peer delay provided by gPTP and the network bridge residence delay are added to calculate the accumulated delays and ensure the latency requirement is met. Control traffic has the third-highest ...
