AudioWG virtual F2F: AudioOutputContext

[guest271314]

AudioWG virtual F2F:

• This is desirable, and can be implemented on some systems fully (Jack on Linux for example, or using kernel extensions on other OSes), but is out of scope of the Web Audio API. This is clearly the responsibility of the WebRTC working group, because they deal with device access and permissions. The security considerations are extremely important: without an explicit user consent, the audio of the machine could be exfiltrated to any website.
• Closing, but we'll follow up in other groups if needed.

As pointed out above, the WG still believes this is out of the scope of Web Audio API.

Is there any specific reason to create a new issue instead of following up on the existing one?

Is there anything wrong with getDisplayMedia({audio: true}) ?

It only captures the tab on Linux and macOS, but captures the computer audio on Windows and Chrome OS. It's an OS limitation, there's not much spec work to do.

[padenot]

Yes, it's possible on Linux desktop as well, but not possible without third-party software on macOS.

Anyway, there is nothing missing on the web platform for this feature, I'm closing this.

getDisplayMedia({audio: true}) allows capturing the device's output, as you note.
