Abstract: A method comprising: at an electronic device (100) having an array microphones (101) with a plurality of microphones and a processor (102): receiving a plurality of microphone signals (x1, x2, x3) from the plurality of microphones; generating a processed signal (XP) from the plurality of microphone signals using one or both of beamforming and deconvolution; generating a compensated processed signal (XO) by compensating the processed audio signal (XP) in accordance with compensation coefficients (Z). Generating the compensated processed signal comprises: generating first spectrum values (PXP) from the processed audio signal; generating reference spectrum values ( ) from multiple second spectrum values (PX1, PX2, PX3) generated from each of at least two of the microphone signals in the plurality of microphone signals (x1, x2, x3); and generating the compensation coefficients (Z) from the reference spectrum values ( ) and the first spectrum values (PXP).
The compensation may improve undesired effects related to e.g. coloration at the output of multi-microphone systems involving e.g. one or both of beamforming and deconvolution of microphone signals from a microphone array.-

Abstract: The present invention discloses an audio signal processing system, a loudspeaker and an electronics device. The audio signal processing system having a clipping threshold estimator, which receives an input audio signal and outputs at least one clipping threshold; and an audio processing unit, which receives the input audio signal, processes the input audio signal to control the non-linear distortion added to the input audio signal based on the clipping threshold and outputs an output audio signal to a loudspeaker driver, wherein the clipping threshold estimator includes: an extraction unit which extracts a set of features from the input audio signal; and a regression or classification unit which receives the set of features and converts the set of features into the at least one clipping threshold by using a regression or classification processing.

Abstract: Disclosed is a headset for audio transmission. The headset is configured to be worn by a user. The headset comprises a speaker for sound transmission into the users ear. The headset comprises a wireless communication unit for communication with an external device. The headset comprises a connection to a location-based service software, the location-based service software is configured for controlling at least one headset feature based on location data of the headset. The headset comprises a processing unit. The processing unit is configured for obtaining current location data of the headset. The processing unit is configured for enabling the location-based service software to detect if the current location data of the headset corresponds to a geographic region for which a first geo-fence is defined by the user. The processing unit is configured for changing the at least one headset feature, if a change criterion associated with the first geofence is satisfied; wherein the change of at least one headset feature is defined by the user.

Abstract: An apparatus, comprising: a manikin with at least a head portion and an ear portion; wherein the head portion has an inner side and an outer side and accommodates a mouth simulator including an electro-acoustic transducer. Further, the apparatus comprises an electrodynamic vibrator with a vibrating rod wherein the vibrating rod is coupled to the manikin to exert a vibrating force at the head portion; and wherein the vibrating force induces vibration of the manikin at least at the ear portion. Thereby more realistic electroacoustic tests on devices under test such as such as headsets, headphones, earphones, hearing instruments and active hearing protectors can be performed.
