Show Notes
Have you ever wondered how a tiny conference speaker can pick up your voice from across a cavernous, echoing room while ignoring the hum of the air conditioner? In this episode, Herman and Corn pull back the curtain on beamforming, a sophisticated blend of physics and digital signal processing that allows devices to "look" with their ears. From the basic principles of wave interference to the cutting-edge world of neural beamforming and spatial audio, this discussion explores how we are using billions of calculations per second to replicate—and sometimes exceed—the natural capabilities of human hearing. Whether it is life-changing hearing aid technology or futuristic soundbars that bounce audio off your walls, learn why the future of sound is all about direction.
