How Smart Speakers Adapt Sound to Your Room and Listening Spot

This patent describes a system that automatically adjusts how spatial audio sounds in a room by sensing speaker locations, listener position, and room acoustics, then dynamically calibrating the sound output.

How a Device Renders Immersive Sound Objects Using Speaker Virtualization

Dolby's patent describes an audio processing system that takes individual sound elements, like a buzzing bee, and places them precisely in a 3D space using smart software that makes speakers sound like they are in different locations.

How to Mix Sound for Different Speaker Setups

This patent describes a system for mixing and playing back audio, allowing sound engineers to precisely control where sounds appear in a room, even preventing sounds from playing through specific speakers.

How Speakers Create Overhead Sound from Ceiling Reflections

This patent describes a system using upward-firing speakers and special sound filters to trick your ears into hearing overhead sounds by reflecting audio off the ceiling.

How Audio Systems Prioritize Sounds for Better Playback

This patent describes how audio systems can sort sounds into important and less important categories, then use different processing power for each to make complex audio, like movie soundtracks, sound better on various speakers.

How a Speaker Bounces Sound Off the Ceiling for Wider Audio

This patent describes a speaker system with special upward-firing drivers and slots designed to bounce high-frequency sound off a ceiling, creating a wider, more immersive listening experience.
