javascript – WebRTC: Is there a way to capture the output audio from another application (e.g., google meet, zoom)?

Web App to tecord both input and output audio from conversations.

For this app I’m using WebRTC media devices.

Scenario:

1. User opens the web app and starts recording.
2. User starts a conversation in another tool (e.g., Google Meet, Zoom, etc.).
3. The web app must record both input (microphone) and output (speakers) audio.

I’ve already managed to record the audio from the microphone, but capturing the output audio (from a bluetooth speaker) is the problem.

Any ideas?
