METHOD FOR SIGNAL PROCESSING OF COOPERATING MICROPHONE RECEIVERS
20230224075 · 2023-07-13 ·

Methods for the distributed reception of receivers without significantly increasing the performance requirements of the system. In particular, this object is achieved by a method which is able to strongly improve the quality of the individual samples and thus of the signal emitted by the network in a receiver network with low complexity, without requiring a central coordinator, by means of a continuous, receiver-internal, independent combination of the received data through separate antennas, or which is able to increase the spatial coverage per receiver while maintaining the same quality of wireless transmission rates per microphone, as well as realize every scenario lying in between these extremes.

Sound masking system

A sound masking system according to the invention is disclosed in which one or more sound masking loudspeaker assemblies are coupled to one or more electronic sound masking signal generators. The loudspeaker assemblies in the system of the invention have a low directivity index and preferably emit an acoustic sound masking signal that has a sound masking spectrum specifically designed to provide superior sound masking in an open plan office. Each of the plurality of loudspeaker assemblies is oriented to provide the acoustic sound masking signal in a direct path into the predetermined area in which masking sound is needed. In addition, the sound masking system of the invention can include a remote control function by which a user can select from a plurality of stored sets of information for providing from a recipient loudspeaker assembly an acoustic sound masking signal having a-selected sound masking spectrum.

Calibration of a playback device based on an estimated frequency response

An example playback device is configured to receive a first stream of audio comprising source audio content to be played back by the playback device and record, via one or more microphones of the playback device, an audio signal output by the playback device based on the playback device playing the source audio content. The playback device is also configured to determine a transfer function between a frequency-domain representation of the first stream of audio and a frequency-domain representation of the recorded audio signal, and then determine an estimated frequency response of the playback device based on a difference between (i) the transfer function and (ii) a self-response of the playback device, where the self-response of the playback device is stored in a memory of the playback device. Based on the estimated frequency response, the playback device is configured to determine an acoustic calibration adjustment and implement the acoustic calibration adjustment.

Vocal guidance engines for playback devices
11698771 · 2023-07-11 · ·

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).
