摘要： A system and method for assisting selective hearing includes a detector for detecting an audio source signal portion of one or more audio sources by using at least two received microphone signals of a hearing environment. A position determiner allocates position information to each of the one or more audio sources. An audio type classifier assigns an audio source signal type to the audio source signal portion of each of the one or more audio sources. A signal portion modifier varies the audio source signal portion of at least one audio source of the one or more audio sources depending on the audio signal type of the audio source signal portion of the at least one audio source so as to obtain a modified audio signal portion of the at least one audio source. The system includes a signal generator.

摘要： A device includes one or more processors configured to receive, via wireless transmission from a playback device, data associated with a pose of the playback device. The one or more processors are also configured to select, based on the data, a particular representation of a sound field from a plurality of representations of the sound field. Each respective representation of the sound field corresponds to a different sector of a set of sectors. A sector represents a range of values associated with movement of the playback device. The one or more processors are further configured to generate audio data corresponding to the selected representation of the sound field. one or more processors are also configured to send, via wireless transmission, the audio data as streaming data to the playback device.

摘要： Embodiments of this application disclose a noise reduction headset. A branch pipe is disposed in the headset to connect a sound cavity inside the headset and an external environment. The branch pipe has a low-pass filter function to filter out high-band noise entering the sound cavity from the external environment, so that impact on sound quality inside the sound cavity that is caused by noise in the external environment is reduced, thereby implementing passive noise reduction.

摘要： An audio apparatus and method employ a first renderer circuit, wherein the first renderer circuit is arranged to render audio elements by generating a first set of audio signals for a set of loudspeakers; and a second renderer circuit, wherein the second renderer circuit is arranged to render audio elements by generating a second set of audio signals for headphones. The audio apparatus and method select between the first renderer circuit and the second renderer circuit such that the rendering of at least a first part of a first audio element is in response to a first audio rendering property indicator which is received in an audio signal. The first audio rendering property indicator is indicative of an audio format of the first audio element.

摘要： An audio system in a local area providing an audio signal to a headset of a remote user is presented herein. The audio system identifies sounds from a human sound source in the local area, based in part on sounds detected within the local area. The audio system generates an audio signal for presentation to a remote user within a virtual representation of the local area based in part on a location of the remote user within the virtual representation of the local area relative to a virtual representation of the human sound source within the virtual representation of the local area. The audio system provides the audio signal to a headset of the remote user, wherein the headset presents the audio signal as part of the virtual representation of the local area to the remote user.
