Spatial Audio Rendering With Modal Beamforming for Flexible Speaker Layouts

The patent applies dynamic adaptation by allowing the audio system to automatically adjust the number and arrangement of virtual speakers based on the physical speaker configuration. The processor dynamically determines virtual speaker positions and audio object placements, enabling the system to adapt to varying physical arrangements without requiring a fixed large number of physical speakers.

The patent creates virtual copies of physical speakers through spatial audio objects. Instead of requiring actual physical speakers in every position, the system generates virtual speaker representations that replicate the acoustic effects. This allows high-fidelity spatial audio rendering with fewer physical speakers by using computational audio objects to simulate the presence of additional speakers.

The system incorporates feedback mechanisms where the processor detects or receives information about the physical speaker arrangement and uses this feedback to automatically adjust the virtual speaker configuration. This closed-loop approach ensures that audio fidelity is maintained regardless of speaker placement by continuously adapting the audio rendering parameters to match the actual physical configuration.

The patent changes critical parameters such as virtual speaker positions, audio object locations, and spatial rendering characteristics based on the detected physical speaker arrangement. By dynamically modifying these parameters, the system maintains optimal audio fidelity across different physical configurations without requiring precise speaker placement.
