Spatial audio for interactive audio environments

Systems and methods of presenting an output audio signal to a listener located at a first location in a virtual environment are disclosed. According to embodiments of a method, an input audio signal is received. For each sound source of a plurality of sound sources in the virtual environment, a respective first intermediate audio signal corresponding to the input audio signal is determined, based on a location of the respective sound source in the virtual environment, and the respective first intermediate audio signal is associated with a first bus. For each of the sound sources of the plurality of sound sources in the virtual environment, a respective second intermediate audio signal is determined. The respective second intermediate audio signal corresponds to a reverberation of the input audio signal in the virtual environment. The respective second intermediate audio signal is determined based on a location of the respective sound source, and further based on an acoustic property of the virtual environment. The respective second intermediate audio signal is associated with a second bus. The output audio signal is presented to the listener via the first bus and the second bus.

Wearable electronic device corrects an error where a user hears binaural sound
11716585 · 2023-08-01 ·

A wearable electronic device (WED) corrects an error where a user hears binaural sound. A processor processes sound into binaural sound that localizes to the user at a location, and the WED determines a gaze direction of the user when the user hears the binaural sound. The WED corrects an error between the location and the gaze direction.

Contact detection via impedance analysis

An electronic device may include one or more terminals configured to provide a voltage signal to an actuator. The electronic device may detect a current associated with the voltage signal provided by the terminal to the actuator. The electronic device may determine an impedance across associated with the actuator based on the voltage signal and the electrical current. The electronic device may compare the impedance to a threshold impedance to determine whether there is sufficient skin contact with the actuator. The electronic device may provide audio via cartilage conduction if there is sufficient contact based on comparing the impedance to the threshold impedance, or may output a notification to the user to adjust placement of the electronic device to improve contact.

TERMINAL FOR CONTROLLING WIRELESS SOUND DEVICE, AND METHOD THEREFOR

A terminal for controlling a wireless sound device can include a communication interface configured to wirelessly connect to at least one or more wireless sound devices; and a processor configured to transmit and receive a positioning signal to and from the at least one or more wireless sound devices, determine a relative position of the at least one or more wireless sound devices based on the positioning signal, receive an acceleration sensor value from the at least one or more wireless sound devices, determine a posture of the at least one or more wireless sound devices based on the acceleration sensor value, determine a wearing state of the at least one or more wireless sound devices based on the relative position and the posture of the at least one or more wireless sound devices, and transmit an audio signal to a worn wireless sound device among the wireless sound devices.

Switching binaural sound from head movements
11711665 · 2023-07-25 ·

A method or apparatus switches between binaural sound and stereo sound in response to head movements of a listener. An electronic device provides the listener with binaural sound at a sound localization point (SLP) in a field-of-view of the listener. Binaural sound at the SLP switches to one of mono or stereo sound when head movements of the listener cause the SLP to move outside the field-of-view.
