When a meeting has audio watermarks, you can upload audio recordings to Control Hub, which then analyzes the recording and looks up the unique identifiers. You can look at the results to see which source client or device recorded the meeting.

  • In order to be analyzed, the recording must be an AAC, MP3, M4A, WAV, MP4, AVI, or MOV file no larger than 500MB.
  • The recording must be longer than 100 seconds.
  • You can only analyze recordings for meetings hosted by people in your organization.
  • Watermark information is retained for the same duration as the organization's meeting information.

Sign in to Control Hub, then under Management, select Organization Settings.


In the Meeting watermarks section, toggle on Add audio watermark.


In Control Hub, under Monitoring, select Troubleshooting.


Click Watermark Analysis.


Search for or select the meeting in the list, then click Analyze.


In the Analyze audio watermark window, enter a name for your analysis.


(Optional) Enter a note for your analysis.


Drag and drop the audio file to be analyzed, or click Choose file to browse to the audio file.


Click Close. When the analysis is complete, it's shown in the list of results on the Analyze watermark page.


Select the meeting in the list to see the results of the analysis. Click Download to download the results.

Factors involved in successfully decoding a recorded watermark include the distance between the recording device and the speaker outputting the audio, the volume of that audio, environmental noise, etc. Our watermarking technology has additional resiliency to being encoded multiple times, as might happen when the media is shared.

This feature is designed to enable successful decoding of the watermark identifier in a broad but reasonable set of circumstances. Our goal is for a recording device, such as a mobile phone, that is lying on a desk near a personal endpoint or laptop client, should always create a recording that results in a successful analysis. As the recording device is moved away from the source, or is obscured from hearing the full audio spectrum, the chances of a successful analysis are decreased.

In order to successfully analyze a recording, a reasonable capture of the meeting audio is needed. If a meeting's audio is recorded on the same computer that is hosting the client, limitations should not apply.
