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.

A device includes a memory configured to store instructions and one or more processors configured to execute the instructions. The one or more processors are configured to execute the instructions to receive audio data including a first audio frame corresponding to a first output of a first microphone and a second audio frame corresponding to a second output of a second microphone. The one or more processors are also configured to execute the instructions to provide the audio data to a first noise-suppression network and a second noise-suppression network. The first noise-suppression network is configured to generate a first noise-suppressed audio frame and the second noise-suppression network is configured to generate a second noise-suppressed audio frame. The one or more processors are further configured to execute the instructions to provide the noise-suppressed audio frames to an attention-pooling network. The attention-pooling network is configured to generate an output noise-suppressed audio frame.

A distributed audio processing system is disclosed, for providing users with the capability of producing a personalized audio mix of a plurality of signals from a plurality of audio sources. The system includes a wireless transmitter for each audio source and, for each user, a wireless receiver. The receiver comprises a programmable audio signal processor configured to process and mix a plurality of audio tracks received via a radio broadcast of a multi-track audio signal comprising the audio signals from the plurality of sources, said processing and mixing being programmable via received commands, instructions and/or parameters. The transmitters are configured to process the audio signals received from their respective sources, according to received commands, instructions and/or parameters. According to an embodiment, a user may provide commands, instructions and/or parameters to any of the receivers and/or transmitters of the system.

A Bluetooth audio broadcasting system includes: an audio broadcasting device arranged to operably broadcast BLE audio packets; a first Bluetooth member device arranged to operably parse the BLE audio packets to acquire a predetermined audio data and to operably control a first audio playback circuit to playback the predetermined audio data; and a second Bluetooth member device arranged to operably parse the BLE audio packets to acquire the predetermined audio data and to operably control a second audio playback circuit to playback the predetermined audio data. After receiving the BLE audio packets from the audio broadcasting device, the first Bluetooth member further adjusts an audio volume of the first audio playback circuit according to a volume adjusting instruction transmitted from another device other than the audio broadcasting device, and the second Bluetooth member further adjusts an audio volume of the second audio playback circuit according to the volume adjusting instruction.

Examples described herein involve configuring a playback device based on distortion, such as that caused by a barrier. One implementation may involve causing the playback device to play audio content according to an existing playback configuration, determining an existing frequency response of the playback device in a given system, and determining whether a difference between the existing frequency response of the playback device in the given system and a predetermined frequency response for the playback device is greater than a predetermined distortion threshold. If it is determined that the difference between the existing frequency response of the playback device and the predetermined frequency response for the playback device is greater than the predetermined distortion threshold, then the existing playback configuration of the playback device is changed to an updated playback configuration of the playback device and the playback device plays audio content according to the updated playback configuration.

A bone conduction speaker is built into a seat of a vehicle and faces the skull of an occupant seated in the seat. An acoustic control ECU individually selects sound to be output from the bone conduction speaker for each of the occupants in the vehicle, according to attribute information of the occupant recorded in a portable terminal device carried by the occupant, and causes the selected sound to be individually output from the bone conduction speaker to each of the occupants.

A specialized audio/instrument cable with built-in digital signal processing capabilities that adds digital audio sampling capabilities that allows the user to trigger synthesized sounds or virtual musical instruments from within the cable itself to affect the sound generated from an instrument or microphone such that the cable is the only connection needed between the instrument or microphone and an output device. Using voice recognition, the specialized cable can select an audio effects chain algorithm and/or sampled sound algorithm extrapolated from a musical digital audio fingerprint (MDAF) created from a desired musician's instrument to alter the sound of the input instrument's audio.
