Audio Processor, System, Method and Computer Program for Audio Rendering

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes an audio processor, system, method, and computer program that optimizes audio playback from loudspeakers according to a listener's position relative to the speakers, and the specific characteristics of those speakers. By dynamically adjusting parameters such as delay, amplitude, and frequency response for each loudspeaker, the audio output can be tailored in real-time or for predefined positions, ensuring the listener experiences consistent and optimal audio quality regardless of where they are located in the room. The system accounts for variations in loudspeaker design (such as emission patterns) and room acoustics to deliver a more uniform listening experience.

Use CasesContent extracted from patent full text and abstract with AI.

• Home theater systems that want to provide high-quality sound throughout a living room, even if listeners are moving around.
• Sound reinforcement in conference rooms or auditoriums to ensure clear audio for all audience members, regardless of seat location.
• Car audio systems where multiple occupants are positioned at different locations and heights.
• Gaming setups where accurate spatial audio is needed as gamers move or change their seating.
• Smart speakers or soundbars that adjust audio output based on users' positions as detected by sensors or cameras.
• Public address (PA) systems in venues, airports, or shopping centers, ensuring clear announcements for all listeners.

BenefitsContent extracted from patent full text and abstract with AI.

• Delivers consistent and optimized audio quality across multiple listener positions, not just at a single 'sweet spot'.
• Automatically adapts to different loudspeaker types and room layouts, making the system versatile.
• Can track listener position and orientation in real-time with sensors, providing dynamic adjustment without manual intervention.
• Improves spatial sound imaging, making the audio experience more immersive and true to the original production intent.
• Allows multiple users in different positions or moving within the listening area to have a high-quality experience simultaneously.
• Reduces the collapse of stereo or surround sound imaging that occurs when listeners move away from the ideal position.

Patent Abstract

An audio processor configured for generating, for each of a set of one or more loudspeakers, a set of one or more parameters, which determine a derivation of a loudspeaker signal to be reproduced by the respective loudspeaker from an audio signal, based on a listener position and loudspeaker position of the set of one or more loudspeakers. The audio processor is configured to base the generation of the set of one or more parameters for the set of one or more loudspeakers on a loudspeaker characteristic of at least one of the set of one or more loudspeakers.
