Latest Patents

One of Yuancheng Luo's latest patents is titled "Surface Augmented Ray-Based Acoustic Modeling." This patent discloses techniques for performing ray-based acoustic modeling that effectively models the scattering of acoustic waves by a device's surface. The acoustic modeling utilizes two parameters: a room response that represents the acoustics and geometry of a room, and a device response that represents the acoustics and geometry of the device. The room response is determined using ray-based acoustic modeling techniques, such as ray tracing. The device response can be measured in an actual environment or simulated, representing the acoustic response of the device to individual acoustic plane waves. The device applies a superposition of the room response and the plane wave scattering from the device response to determine acoustic pressure values and generate microphone audio data. Additionally, the device can estimate room impulse response (RIR) data using data from the microphones, which can be utilized for audio processing tasks such as sound equalization, acoustic echo cancellation, and audio beamforming.

Another notable patent is "Loudspeaker Beamforming for Improved Spatial Coverage." This system is designed to enhance the spatial coverage of output audio and improve the user experience by performing upmixing and loudspeaker beamforming on stereo input signals. The system can upmix the stereo input signal to extract a center channel and generate three-channel audio data. Subsequently, it performs loudspeaker beamforming on the three-channel audio data, allowing two loudspeakers to produce output audio with three distinct beams. Users can perceive these beams as originating from three separate locations, creating a wide virtual sound stage despite the loudspeakers being closely spaced.
