Technology described in this document can be embodied in an earpiece of an active noise reduction (ANR) device. The earpiece includes a plurality of microphones, wherein each of the plurality of microphones is usable for capturing ambient audio to generate input signals for both an ANR mode of operation and a hear-through mode of operation of the ANR device. The earpiece further includes a controller configured to: process a first subset of microphones from the plurality of microphones to generate input signals for the ANR mode of operation, process a second subset of microphones from the plurality of microphones to generate input signals for the hear-through mode of operation, detect that a particular microphone of the second subset is acoustically coupled to an acoustic transducer of the ANR device in the hear-through mode of operation, and in response to the detection, process the input signals from the second subset of microphones without using input signals from the particular microphone.

An communication system supports communication paths within an environment by receiving speech signals of a speaker and playing it back for one or more listeners. Signal processing tasks are split into a microphone related part and into a loudspeaker related part. A sound processing system suitable for use in an environment having multiple acoustic zones includes a plurality of microphone communication instances coupled and a plurality of loudspeaker instances.

A system and method for routing the audio output from a selected one of a plurality of independent audio sources to an audio system for amplification/playback; the routing being based upon the movement of a user's head, and in particular the user's line-of-sight inferred from the movement. The invention employs a spatial mapping of the plurality of audio sources and routes the respective audio output of each of the sources to the audio amplification/playback system upon making the determination that the user's line-of-sight is being directed to a particular one of the audio sources.

A method and a device for switching a master earphone with a slave earphone of TWS earphones in a call scenario, and a medium are provided. In the method for switching a master earphone with a slave earphone of TWS earphones in a call scenario according to the present disclosure, a signal indicating a position change of the master earphone being worn relative to a wearing part of the master earphone and a signal indicating a position change of the slave earphone being worn relative to a wearing part of the slave earphone are obtained; it is determined whether the signals meet a master-slave earphone switching condition; and in a case that the signals meet the master-slave earphone switching condition, the master earphone is controlled to operate in a slave earphone mode and the slave earphone is controlled to operate in a master earphone mode.

An integrated circuit for digital signal routing. Signal routing is achieved with a multiply-accumulate block, which takes data from one or more data sources and, after any required scaling, generates output data for a data destination. Data from a data source is buffered for an entire period of a data sample clock so that the multiply-accumulate block can retrieve the data at any point in the period, and output data of the multiply-accumulate block is buffered for an entire period of the data sample clock so that the data destination can retrieve the data at any point in the period. The multiply-accumulate block operates on a time division multiplexed basis, so that multiple signal paths can be processed within one period of the sample clock.

The disclosure herein provides a mobile system including a mobile base station and a wireless earbud. The base station comprising a connection hole, a user input button, at least one processor, at least one memory, and circuitry. The wireless earbud is configured for plugging into the connection hole of the base station to form an integrated body with the base station. The system establishes a wireless Bluetooth pairing between a smartphone and the wireless earbud using two-way wireless communication to produce Bluetooth communication between the smartphone and the wireless earbud.

An electronic device is provided. The electronic device includes a processor and a memory storing instructions which, when executed by the processor, cause the processor to obtain information of a wireless audio device wirelessly connectable to the electronic device, determine whether an utterance of a user is a device-controlling utterance for a target device which is a target of remote control in response to the information of the wireless audio device, and suggest switching a connection of the wireless audio device to the target device based on an intent in the utterance of the user. Other example embodiments, in addition to the foregoing example embodiment, are also applicable.

A peak current limiter for an audio system comprising at least two audio amplifiers is described. The peak current limiter comprises at least two audio inputs; at least two audio outputs, each audio output being coupled to a respective one of the at least two audio inputs and configured to be coupled to a respective one of the at least two audio amplifiers. The peak current limiter is configured to receive an audio signal on each of the respective audio inputs. The peak current limiter determines a current value required by each of at least two audio amplifiers. An audio characteristic of at least one of the received audio signals is modified to limit the total current supplied to the at least two amplifiers below a predefined maximum current value.

The present disclosure relates to a method, a device, and a computer program for controlling and managing a state of a peripheral device in a wireless communication system, and a recording medium therefor. According to an embodiment of the present disclosure, a method for changing an audio stream session-related state may include the steps of: acquiring information relating to a current audio stream session-related state of a second device before a first device in a first audio stream session-related state performs transition of an audio stream session-related state; determining a second audio stream session-related state of the first device at least on the basis of the current audio stream session-related state of the second device; and performing the transition of the audio stream session-related state by the first device on the basis of the second audio stream session-related state.
