A technique for producing audio includes providing multiple audio tracks of respective sound sources of an audio performance and rendering a sound production of the audio performance at a listening venue by playing back the audio tracks on respective playback units.

An audio apparatus adaptable to a user position is provided. The audio apparatus may include a plurality of sub-modules placed at separate locations from one another, each sub-module of the plurality of sub-modules including a loudspeaker configured to generate sound and a communicator configured to perform communication. The first sub-module among the plurality of sub-modules may include a processor that processes an audio signal to be output as sound through the loudspeaker of the first sub-module, determines a user's position with respect to each of the plurality of sub-modules, and changes a state of the sound being output from the loudspeaker of the first sub-module in accordance with the determined position of the user.

Systems and methods for vocal guidance for playback devices are disclosed. A playback device can include a first wireless transceiver for communication via a first data network and a second wireless transceiver for communication via a second data network. The device includes one or more processors and is configured to maintain a library that includes one or more source device names and corresponding audio content, the audio content configured to be played back via an amplifier to indicate association of a particular source device with the playback device via the first data network. The device receives, via the second data network, information from one or more remote computing devices, and based on the information, updates the library by: (i) adding at least one new source device name and corresponding audio content; (ii) changing at least one source device name or its corresponding audio content; or both (i) and (ii).

Example techniques involve noise-robust acoustic echo cancellation. An example implementation may involve causing one or more speakers of the playback device to play back audio content and while the audio content is playing back, capturing, via the one or more microphones, audio within an acoustic environment that includes the audio playback. The example implementation may involve determining measured and reference signals in the STFT domain. During each n.sup.th iteration of an acoustic echo canceller (AEC): the implementation may involve determining a frame of an output signal by generating a frame of a model signal by passing a frame of the reference signal through an instance of an adaptive filter and then redacting the n.sup.th frame of the model signal from an n.sup.th frame of the measured signal. The implementation may further involve determining an instance of the adaptive filter for a next iteration of the AEC.

At least one of the present exemplary embodiments and methods introduces a unique Audio Collection System comprised of self-contained Audio Collection Devices (ACDs), Audio Distribution Devices (ADDS), and Audio Control Analysis (ACA) components/functions. The system may be used to gather audio signals from environments in ways that are not presently available with the intention being to gather audio, analyze, and learn what may be understood about a given environment or situation.

One exemplary feature of this system is that it introduces a set of standardized modular components that can be scaled from a small configuration to larger systems. For example, systems that may manage large numbers of audio input streams, broadcast audio streams, modify audio streams, combine and track sounds, and present sound as immersive experience. Additional features will provide other various controls and statistical capabilities, as described herewith.

The present invention relates to the technical field of mobile terminals. Disclosed are an audio signal processing method and apparatus, a device, and a storage medium. The method comprises: when detecting that 3.5 mm earphones are connected by means of a type-C plug of a transfer cable, a mobile terminal determines whether states of audio channels of an audio ground GND and a microphone MIC of the type-C plug are correct. When determining that the states of the audio channels of the GND and the MIC of the type-C plug are correct, the mobile terminal decides whether to enter an audio mode. If the mobile terminal decides to enter the audio mode, a low-resistance network for reducing channel impedance is controlled to connect in parallel to the GND.

An apparatus, method and computer program product for: providing spatial audio signals for output for a first user via a first audio device and a second audio device, receiving an indication of deactivation of the second audio device, receiving an indication that the second audio device is re-activated by a second user, and performing, in response to receiving the indication that the second audio device is re-activated by the second user, a modification of the spatial audio signals.

A distribution assistance apparatus and a distribution assistance method are provided. An input and output IF mixes a sound input from an HS microphone or a built-in microphone with a sound signal of distribution data received from a portable terminal and outputs the sound. Even when an addition process or an effect is applied to distribution data in the portable terminal, a sound input from the HS microphone or the built-in microphone can be output through a monitor at that point in time without causing a latency.

A signal processing apparatus and a signal processing method are provided. In a case where an HS microphone detection circuit has just detected connection of a microphone contact point, an input and output IF blocks a sound signal which is input from the microphone contact point from a first input port of a sound processing apparatus for two seconds by an HS mute circuit. Thereby, it is possible to prevent an improper sound signal from the microphone contact point from being output from a left speaker and a right speaker of a headset through a right output port Rout and a left output port Lout of the sound processing apparatus. Therefore, it is possible to prevent unpleasant noise caused by the improper sound signal from being output to a user.

Technology for grouping, consolidating, and pairing individual playback devices with network capability (players) to stimulate a multi-channel listening environment is disclosed. An example method includes receiving an audio signal containing a range of audio frequencies; amplifying, according to a gain parameter, the audio signal to be reproduced by at least one speaker. The example method includes automatically increasing the gain parameter to a higher gain parameter responsive to a determination that no more than a subset of the range of audio frequencies is to be reproduced by the at least one speaker. The example method includes amplifying, according to the higher gain parameter, the audio signal containing no more than the subset of the range of audio frequencies to be reproduced by the at least one speaker.
