Explainer None Specification https://www.w3.org/TR/screen-capture/#dfn-restrictownaudio Summary restrictOwnAudio is a captured display surfaces constrainable property. This constrainable property changes the behavior of system audio in a captured display surface. The restrictOwnAudio constraint will only have an effect if the captured display surface inherently includes system audio; otherwise, it will have no impact. By default, when system audio is captured, it includes all audio played out by the system on audio output devices. When restrictOwnAudio is enabled, the captured system audio will be filtered to exclude audio originating from the document that performed getDisplayMedia. The restrictOwnAudio constraint allows for cleaner screen recordings for some use cases. Without it, if the capturing web page itself is playing audio (eg a video embedded on the on the recording page), that audio would be included in the capture. This could lead to an undesirable echo or interfere with the intended audio sources from other tabs or applications.
