Keep notification sounds out of the audience audio

Notification control needs both an operating-system check and a check of which application sounds are included in the broadcast mix.

A useful audio check follows the signal from its source to the recording that a viewer actually receives. Keep a short reference sentence and change one control at a time. Write down the source, device, playback route and recording route so a later adjustment can be reversed. Listen to the saved result as well as the monitoring output; those are different checkpoints.

A practical procedure

1. List applications that can make sounds, including browsers, chat tools and calendar reminders.

2. Disable unnecessary alerts and separate production audio from general desktop audio where your setup permits.

3. Send a test notification during a private recording and confirm it is absent from the saved audience mix.

Worked example: a fictional session

A fictional moderator receives messages on a separate device while the broadcast computer records only the selected host and demonstration sources.

Check the limits

Silencing a visible notification does not prove that every background application's sound is excluded.
