With “Adaptive audio,” you and your team can join Google Meet using multiple laptops in close proximity without awkward echos and audio feedback. Adaptive audio in Meet will automatically detect the presence of multiple laptops in the room and synchronize the microphones and speakers for a seamless audio experience. Most importantly, adaptive audio gives users the flexibility to join meetings when meeting rooms are not available, meeting room hardware is not working, or for smaller organizations, when there isn’t dedicated video conferencing equipment in every room.
