×

Full-room mic pickup

Our Microphone Mist™ technology fills large spaces with thousands of virtual microphones, so there’s always one nearby. People in the room can be confident they’ll always be heard by those who are remote.

×

Continuous autocalibration

There’s no need to calibrate your HDL300 manually. It’s always adapting to changes in your room’s acoustic profile, so even if you adjust the furniture or layout, the audio will still sound great.

×

Intelligent Sound Targeting

HVAC and other unwanted sounds can seriously affect your audio performance. So, instead of trying to suppress these noises after the fact, we use adaptive learning algorithms to preemptively ignore them.

×

Rapid conversation tracking

Our technology quickly switches pickup from talker to talker, no matter where they are in the room. Conversations sound natural, even when multiple voices overlap.

×

Position-based gain control

We apply gain separately to each sound in a space based on its position, creating a smooth and natural listening experience for remote participants.
