摘要： A system is disclosed for using an audio time and level difference renderer (TLDR) to generate spatialized audio content for multiple channels from an audio signal received at a single channel. The system selects an audio TLDR from a set of audio TLDRs based on received input parameters. The system configures the selected audio TLDR based on received input parameters using a filter parameter model to generate a configured audio TLDR that comprises a set of configured binaural dynamic filters, and a configured delay between the multiple channel. The system applies the configured audio TLDR to an audio signal received at the single channel to generate spatialized multiple channel audio content for each channel of the multiple audio channel and presents the generated spatialized audio content at multiple channels to a user via a headset.

摘要： A system receives audio data in a frequency range of 20 Hz-20 kHz. The received audio data is encoded by the system into ultrasonic data in frequencies that are greater than 20 kHz, and transmitted into a local area that is proximal to the transmitting device, i.e., within the transmission range of the transmitting device. An ultrasonic communication device that is located in the transmission range of the transmitting device may receive the ultrasonic data. The received ultrasonic data is decoded by the ultrasonic communication system in the receiving device into audio data in a frequency range of 20 Hz-20 kHz, and subsequently presented to a user of the receiving ultrasonic communication device.

摘要： An audio system for spatializing virtual sound sources is described. A microphone array of the audio system is configured to monitor sound in a local area. A controller of the audio system identifies sound sources within the local area using the monitored sound from the microphone array and determines their locations. The controller of the audio system generates a target position for a virtual sound source based on one or more constraints. The one or more constraints include that the target position be at least a threshold distance away from each of the determined locations of the identified sound sources. The controller generates one or more sound filters based in part on the target position to spatialize the virtual sound source. A transducer array of the audio system presents spatialized audio including the virtual sound source content based in part on the one or more sound filters.
