AudioContext: outputLatency property
Baseline
2025
Newly available
Since March 2025, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The outputLatency read-only property of
the AudioContext Interface provides an estimation of the output latency
of the current audio context.
This is the time, in seconds, between the browser passing an audio buffer out of an audio graph over to the host system's audio subsystem to play, and the time at which the first sample in the buffer is actually processed by the audio output device.
It varies depending on the platform and the available hardware.
Value
A double representing the output latency in seconds.
Examples
js
const audioCtx = new AudioContext();
console.log(audioCtx.outputLatency);
