{{APIRef("Audio Session API")}}{{SeeCompatTable}}
The audioSession read-only property of the {{domxref("Navigator")}} interface returns the {{domxref("AudioSession")}} object for the current document.
The {{domxref("AudioSession")}} interface can be used to control how audio from a web application interacts with other audio playing on a device, for example, allowing developers to specify whether their application's audio should play on its own, or along with other device audio.
An {{domxref("AudioSession")}} object.
The following example sets the audio session type to "play-and-record" before starting a video call:
navigator.audioSession.type = "play-and-record";
// Start video call
const stream = await navigator.mediaDevices.getUserMedia({
audio: true,
video: true,
});
localVideo.srcObject = stream;
