Abstract: For video applications, a method for dynamically switching from a current ROI to a target ROI is disclosed, wherein the target ROI only includes active speakers. Advantageously, if the target ROI crops a non-speaker, then the target ROI is expanded to include said non-speaker. Transitioning from the current ROI to the target ROI may be achieved based on a cutover transition technique, or a smooth transition technique. The cutover transition technique achieves the change from the current arrived to the target ROI in a single interval, whereas the smooth transition technique achieves the change over a number of intervals, wherein a percentage of the total change required is allocated to each interval. A system for implementing the above method is also disclosed.

Abstract: A computer-implemented method for processing audio input data into processed audio data by using an audio device comprising a microphone, a processor device and a memory holding a plurality of neural networks is presented. The plurality of neural networks are associated with different room types, wherein each room type is associated with one or more reference room acoustic metrics. The method comprises obtaining, by the microphone, room response data, wherein the room response data is reflecting room acoustics of a room in which the audio device is placed, determining, by using the processor device, the one or more room acoustic metrics based on the room response data, and selecting, by using the processor device, a matching neural network among the plurality of neural networks by comparing the one or more room acoustic metrics with the one or more reference room acoustic metrics associated with the different room types associated with the plurality of neural networks.

Abstract: Disclosed is a headset for audio communication, a software application for an electronic device associated with a headset, and a method for controlling a headset feature. The headset is configured to be worn by a user. The headset comprises a speaker for sound transmission into the user's ear, a transceiver or a radio communication unit for communication with an external device, 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, and a processing unit. The processing unit is configured for enabling the location-based service software to detect if the current location data of the headset indicates a change in location data corresponding to a certain change criterion and changing the at least one headset feature, if a change criterion associated with the change in location data is satisfied.

Abstract: Disclosed is an annular ear cushion for an earphone configured to be worn at an ear of a user. The ear cushion is configured to abut the head of the user along an annular contact surface of the ear cushion and to abut or face a housing of the earphone along an annular attachment surface of the ear cushion when the user is wearing the earphone in its intended position, thereby reducing the level of sound entering the ear canal of the user from the environment. The ear cushion further comprising an annular exterior surface and an annular interior surface each extending from the contact surface to the attachment surface and facing respectively the environment and the ear canal of the user when the user is wearing the earphone in its intended position. The ear cushion further comprising a foam core (150) having a first acoustic impedance, and a cover having a first portion extending across the exterior surface and a second portion extending across the contact surface. The first portion of the cover has a second acoustic impedance that is greater than the first acoustic impedance, wherein that at least one first subportion of the second portion of the cover has a third acoustic impedance that is smaller than the second acoustic impedance.
