The Audio Watermark, or Audio Signature, feature 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: The file shared with Zoom for identification must have audio of at least 2 minutes in length.
