Adding audio watermark
The audio watermark, or audio signature, embeds a user's personal information into the audio as an inaudible watermark if they record during a meeting. If the audio file is shared without permission, Zoom can help identify which participant recorded the meeting.
Note: This option requires enabling the meeting options Only signed-in users can join the meeting or Only signed-in users with specified domains can join meetings.
