This disclosure provides methods, devices, and systems for videoconferencing. The present implementations more specifically relate to audio signal processing techniques that can be used to identify speakers in a videoconference. In some aspects, an audio signal processor may map each speaker in a videoconference to a respective spatial direction and transform the audio signals received from each speaker using one or more transfer functions associated with the spatial direction to which the speaker is mapped. The audio signal processor may further transmit the transformed audio signals to an audio output device that emits sounds waves having a directionality associated with the transformation. For example, the audio signal processor may apply one or more head-related transfer functions to the audio signals received from a particular speaker so that the sound waves emitted by the audio output device are perceived as originating from the spatial direction to which the speaker is mapped.

A hearing aid that includes a microphone, a signal processor, and a speaker transmits a signal to a computer. The signal transmitted to the computer can be the input to the microphone (before processing) or the output to the speaker (after processing). This enables the capturing of a HRTF that does not or that does include the enhancements of the hearing aids.

Embodiments relate to binaural spatialization of more than two sound sources on two audio channels of an audio system. Sound signals each emitted from a corresponding sound source are collected, and a respective virtual position within an angular range of a sound scene is assigned to each sound source. Multi-source audio signals are generated by panning each sound signal according to the respective virtual position. A first multi-source audio signal is spatialized to a first direction to generate a first left signal and a first right signal. A second multi-source audio signal is spatialized to a second direction to generate a second left signal and a second right signal. A binaural signal is generated using the first left signal, the second left signal, the first right signal, and the second right signal. The binaural signal is such that each sound source appears to originate from its respective virtual position.

A method and corresponding system for correcting for deviations in a performance that includes a plurality of audio sources, the method comprising detecting a parameter relating to an audio source, determining if the parameter deviates from a predetermined characteristic and in response to it being determined that the parameter deviates from the predetermined characteristic, causing display of a user interface configured to control the parameter, to allow a user to correct the deviation.

Apparatus is configured to associate each of one or more spatially-distributed audio sources in a virtual space, each audio source providing one or more audio signals representing audio for playback through a user device, with a respective fade-in profile which defines how audio volume for the audio source is gradually increased from a minimum level to a target volume level as a function of time. It is configured also to identify, based on user position, a current field-of-view within a virtual space and, in response to detecting that one or more new audio sources have a predetermined relationship with respect to the current field-of-view, fading-in the audio from the or each new audio source according to the fade-in profile for the respective audio source so as to increase their volume gradually towards the target volume level defined by the fade-in profile.

An audio system for a headset includes a plurality of speakers and an audio controller. The plurality of speakers may be in a dipole configuration that cancel sound leakage into a local area of the headset. The controller filters audio content presented by the plurality of speakers to further mitigate leakage of audio content into the local area. The audio determines sound filters based on environmental conditions, such as ambient noise levels, as well as based on the audio content being presented.

Methods and apparatus for spatial audio navigation that may, for example, be implemented by mobile multipurpose devices. A spatial audio navigation system provides navigational information in audio form to direct users to target locations. The system uses directionality of audio played through a binaural audio device to provide navigational cues to the user. A current location, target location, and map information may be input to pathfinding algorithms to determine a real world path between the user's current location and the target location. The system may then use directional audio played through a headset to guide the user on the path from the current location to the target location. The system may implement one or more of several different spatial audio navigation methods to direct a user when following a path using spatial audio-based cues.

A system, method, and wireless earpieces for communicating with a virtual reality headset. A position and an orientation of a head of a user are detected utilizing at least wireless earpieces. Audio content is received. The audio content is enhanced utilizing the position and the orientation of the head of the user. The audio content is immediately delivered to the user. The method may further include communicating the position and the orientation of the head of the user to the virtual reality headset. The audio content may be based on the orientation and position of the head of the user.

A reproduction device includes: an acquisition unit configured to acquire sound source information about a sound source; a determination unit configured to determine an output characteristic of the sound source with a virtual speaker arranged in a virtual space, based on a positional relationship between the virtual speaker and a virtual listener arranged in the virtual space; and a reproduction unit configured to reproduce the sound source with a real speaker arranged in a real space, based on the output characteristic determined by the determination unit.

A method provides binaural sound to a listener while the listener watches a movie so sounds from the movie localize to a location of a character in the movie. Sound is convolved with head related transfer functions (HRTFs) of the listener, and the convolved sound is provided to the listener who wears a wearable electronic device.
