Enable audio watermarks

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.

Features and limitations

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.

Enable visual watermarks

Visual watermarks superimpose a watermark image over the meeting video and shared content. Each meeting participant sees a watermark image with their own email address. If a meeting participant isn't signed in to Webex, the watermark includes their display name and email address. Users can adjust the watermark opacity so the pattern is visible but doesn't cause too much distraction.

Local recordings are disabled when visual watermarks are turned on. Hosts can still make network-based recordings in meetings with visual watermarks.

To further customize visual watermarks in your organization, check the corresponding options:

  • Allow hosts to control visual watermarks as optional—Hosts can choose to disable visual watermarks in their meetings.
  • Allow network-based recording without visual watermarks—Hosts can make network-based recordings in meetings with visual watermarks enabled. When this option is disabled, hosts aren't able to record any meetings with visual watermarks.
    Visual watermarks don't appear in meeting recordings.
  • Add meeting numbers to visual watermarks—Visual watermarks include the meeting number in addition to each user's unique identifier.
    This option is only available in the Webex Suite meeting platform.
