- iOS and Android devices listen for ultrasonic sounds to know if they are in a meeting room
- Companion Mode emerges as the preferred option to participate
- It’s also easier to share audio on calls
Google Meet has been updated to automatically detect meeting rooms, making Companion Mode the preferred method of joining to reduce echo and audio feedback associated with multiple active microphones nearby.
With this meeting room registration, Google Meet will also automatically check users in to that call so administrators can track attendance.
The feature works on Android and iOS devices, perfect for secondary devices and supports both Meet and Gmail apps.
Google Meet makes it easier to join via companion mode
The system works when the primary device or conference hardware in a meeting room emits an ultrasonic sound that is silent to the human ear. Compatible devices can hear this and by default will operate the Companion Mode setting and check you in.
“To automatically check you in, the green room uses your phone or tablet’s microphone to detect an ultrasonic signal from the conference room’s hardware, streamlining the process and eliminating unnecessary steps.”
Administrators can enable or disable this proximity detection at the room level, but Google did not make it clear whether end users can opt out of using the feature.
Automatic room check-in with Companion Mode support has already started rolling out to all Google Workspace users, including individual account holders, but some domains may be slower than others to get it.
And separately, for those times you need to share audio, Google has made it easier to share audio directly from third-party media apps when using Chrome on the desktop to further reduce the chances of hearing echoes. Now available to all users, Google admitted that this long-missing feature was “highly requested” by its users.
