METHOD AND SYSTEM FOR MAINTAINING TRACK LENGTH FOR PRE-RENDERED SPATIAL AUDIO

A method performed by a programmed processor of an audio system, the method includes receiving a sound track that has a track length, producing a binaural audio version of a sound track, the binaural audio version having an extended track length performing a fading operation upon the binaural audio version to gradually reduce a signal level of the binaural audio version to below a signal threshold level at a time along the extended track length that corresponds to an end time of the track length of the sound track; and storing the binaural audio version having the track length of the sound track in memory for later transmission to an audio playback device for driving one or more speakers.

Methods and apparatus provide digital media with spatial audio to a blockchain. The blockchain network executes a decentralized application (Dapp) with a user interface (UI) that enables a user to select audio for spatialization and uploading to the blockchain. The spatial audio transmits to the blockchain network to reduce processing and transmission of network data.

Ear-worn electronic device for conducting and monitoring mental exercises

An ear-worn electronic device includes a right ear device comprising a first processor and a left ear device comprising a second processor communicatively coupled to the first processor. A physiologic sensor module comprises one or more physiologic sensors configured to sense at least one physiologic parameter from a wearer. A motion sensor module comprises one or more sensors configured to sense movement of the wearer. The first and second processors are coupled to the physiologic and motion sensor modules. The first and second processors are configured to produce a three-dimensional virtual sound environment comprising relaxing sounds, generate verbal instructions within the three-dimensional virtual sound environment that guide the wearer through a predetermined mental exercise that promotes wearer relaxation, and generate verbal commentary that assesses wearer compliance with the predetermined mental exercise in response to one or both of the sensed movement and the at least one physiologic parameter.

Audio apparatus and method of operation therefor

An audio apparatus, e.g. for rendering audio for a virtual/augmented reality application, comprises a receiver (201) for receiving audio data for an audio scene including a first audio component representing a real-world audio source present in an audio environment of a user. A determinator (203) determines a first property of a real-world audio component from the real-world audio source and a target processor (205) determines a target property for a combined audio component being a combination of the real-world audio component received by the user and rendered audio of the first audio component received by the user. An adjuster determines a render property by modifying a property of the first audio component indicated by the audio data for the first audio component in response to the target property and the first property. A renderer (209) renders the first audio component in response to the render property.

Audio system for dynamic determination of personalized acoustic transfer functions

An eyewear device includes an audio system. In one embodiment, the audio system includes a microphone array that includes a plurality of acoustic sensors. Each acoustic sensor is configured to detect sounds within a local area surrounding the microphone array. For a plurality of the detected sounds, the audio system performs a direction of arrival (DoA) estimation. Based on parameters of the detected sound and/or the DoA estimation, the audio system may then generate or update one or more acoustic transfer functions unique to a user. The audio system may use the one or more acoustic transfer functions to generate audio content for the user.

Provided is an information processing apparatus that includes a determination unit and a display control unit. The determination unit obtains a position of a virtual object relative to a display region and determines whether or not a correction allowable region set in a region different from the virtual object overlaps at least a part of the display region when the virtual object is located outside the display region. The display control unit causes at least a part of a display object showing the virtual object in the display region to be displayed in a case where the determination unit determines that the correction allowable region overlaps at least the part of the display region.

Selecting spatial locations for audio personalization

An audio system generates customized head-related transfer functions (HRTFs) for a user. The audio system receives an initial set of estimated HRTFs. The initial set of HRTFs may have been estimated using a trained machine learning and computer vision system and pictures of the user's ears. The audio system generates a set of test locations using the initial set of HRTFs. The audio system presents test sounds at each of the initial set of test locations using the initial set of HRTFs. The audio system monitors user responses to the test sounds. The audio system uses the monitored responses to generate a new set of estimated HRTFs and a new set of test locations. The process repeats until a threshold accuracy is achieved or until a set period of time expires. The audio system presents audio content to the user using the customized HRTFs.

Own voice reinforcement using extra-aural speakers

A system including an audio source device having a first microphone and a first speaker for directing sound into an environment in which the audio source device is located and a wireless audio receiver device having a second microphone and a second speaker for directing sound into a user's ear. The audio source device is configured to 1) capture, using the first microphone, speech of the user as a first audio signal, 2) reduce noise in the first audio signal to produce a speech signal, and 3) drive the first speaker with the speech signal. The wireless audio receiver device is configured to 1) capture, using the second microphone, a reproduction of the speech produced by the first speaker as a second audio signal and 2) drive the second speaker with the second audio signal to output the reproduction of the speech.
