Abstract: Sound capturing apparatus for spatial audio processing comprises: a body 11 which may be spherical or a cuboid; and a plurality of microphones 12 arranged in a predetermined geometry relative to the body such that the apparatus is configured to capture sound substantially from all directions around the body to produce direction and ambience information for the captured sound. Electronics for processing signals from the plurality of microphones may be located partly or wholly within the body. The body may include a protruding element 16 for controlling direction of the body, for handling the apparatus and/or for indicating a preferred direction. The body may also comprise a plurality of cameras or motion sensors. The apparatus is arranged to minimise acoustic shadowing or other undesired interference caused by a human operator handling the apparatus.

Abstract: An external cover device 200 for eg. a phone contains microphones 212, 214, an audio processor 216, for eg. beamforming and a conductive docking terminal 210 allowing connection to a primary terminal 100 containing its own microphones 105, 106. A controller in the terminal 106 processes the signals from both sets of microphones (eg. forward facing in the terminal and rear facing in the cover) according to a cover ID 218, having determined that the cover is attached. The processing may reduce distortion detected in the signals and apply noise-cancellation.

Abstract: One or more operating conditions of a device such as a mobile phone are determined (802). A selection of a mode of operation of the device from at least a first mode and a second mode is facilitated (806, 808) based on the one or more operating conditions of the device such as the time delay between times of arrival of the audio signals (804). In the first mode; the device is configured to detect an operation input received from an audio source based on two or more audio sensors of the device. In the second mode, the device is configured to detect the operation input based on at least one of the two or more audio sensors and at least one non-audio sensor of the device.

Abstract: The method comprises receiving a first microphone signal from a first microphone having a first frequency response characteristic at frequencies associated with wind noise and receiving a second microphone signal from a second microphone having asecond frequency response characteristic at frequencies associated with wind noise. The first frequency response characteristic 1101 provides less gain than the second frequency response characteristic 1102 over the range of frequencies associated with wind noise 114. The first and second microphone signals are then processed (fig 3) to detect the presence of wind noise.

Abstract: Receiving a first audio signal during an application execution in an apparatus, determining a volume level of a volume control interface for controlling a volume level of the first audio signal, controlling processing the first audio signal by at least one digital signal processing algorithm determined on the basis of the determined volume level of the volume control interface for controlling the volume level of the first audio signal, and outputting the controlled processed first audio signal at the determined volume level of the volume control interface. Embodiments of the invention include receiving a second audio signal during a second application execution in the apparatus simultaneously with the first audio signal, processing the second audio signal by at least one digital signal processing algorithm determined on the basis of the determined volume level of the second audio signal and outputting the second audio signal at the determined volume level of the second audio signal. The device provides a user a possibility to control both audio signals (e.g. music and voice) using a single volume control interface. The volume levels of all played audio signals can be changed alternatingly at intervals when the volume control interface is operated.

Abstract: The audio transducer comprises at least one air displacement component, such as a diaphragm and a housing configured to retain the at least one air displacement component. The audio transducer comprises self-healing material so that at least part of the air displacement component or housing comprise the self-healing material. The self-healing material can enable repair of the audio transducer when the audio transducer is deformed and/or if there are any other defects within the audio transducer. Upon detection of such deformation and/or defects a trigger signal is generated to initiate the self-healing process. The self-healing process may be initiated by the application of heat.

Abstract: A spatial audio rendering system receives audio data with a defocus direction 202 and renders the audio scene 207 so as to de-emphasize sources in that direction. Parameters and metadata (eg. source direction, energy ratios or gain in frequency sub bands) are calculated, and angular differences between defocus directions and loudspeaker directions allow adaptive gain computations.

Abstract: An apparatus 1 comprising: an audio transducer 3; a two-dimensional sensing portion 5; and electronic circuitry 3. In operation the sensing portion detects one or more operating conditions of the loudspeaker and provides an output signal to the electronic circuitry which uses said signal to control the audio signal. The two dimensional material comprises at least one of: graphene; graphene oxide; reduced graphene oxide; functionalized graphene; molybdenum disulphide; tungsten disulphide; or boron nitride. The sensing portion may be inside the loudspeaker and provide an indication of a change in conductivity of the two-dimensional material in response to operating conditions of the audio transducer such as temperature, humidity, light or analytes in one or more parts of the loudspeaker. The 2D sensing material (9, Fig. 5) may comprise a conductive material coupled to a voice coil; diaphragm (21, Fig. 5); magnet (31, Fig. 5); or bottom plate of the loudspeaker. The sensing portion may also provide a heat sink function. Control of the audio signal may comprise adjusting the driving voltage.

Abstract: Capturing an acoustic signal by a microphone of an apparatus such as a mobile phone or tablet to generate an electrical output signal. The acoustic signal is rendered in response to a source audio signal by a speaker through at least one speaker interface element of the apparatus 502. The electrical output signal is compared to the source audio signal in order to determine whether the electrical output signal is being affected by mechanical vibrations caused at least partially by the speaker interface element being at least partially interfered by a user such as the users finger pressed against the speaker 504. A predetermined action, which may be muting a call, pausing music or switching off an alarm, is performed in the apparatus whenever it is determined that the electrical output signal is affected by the mechanical vibrations caused at least partially by the speaker interface element being at least partially interfered by the user 506 which may be determined by a difference signal being greater than a threshold.
