    Abstract: A method at a wearable electronic device with: a first electro-acoustic input transducer and a second electro-acoustic input transducer arranged to pick up a first acoustic signal and convert the first acoustic signal to a first microphone signal and second microphone signal; and a third electro-acoustic input transducer arranged to pick up a second acoustic signal and convert the second acoustic signal to a third microphone signal; and a processor (140). The method comprises: generating a beamformed signal based on the first microphone signal (x1) and the second microphone signal; estimating a first frequency value representing a fundamental frequency in one or more of: the first microphone signal, the second microphone signal and the third microphone signal; configuring a first filter with one or more passbands at one or more integer multiples of the first frequency value and one or more stop bands adjacent the one or more stop bands; and filtering, using the first filter, one or more of: the first microphone signal, the second microphone signal and the beamformed signal.

    Abstract: Disclosed is a method and a system configured to be arranged at a location. The system being configured for visual and auditory communication between one or more at-location participants and one or more far-end participants. The system comprising an audio/video (AV)-system. The AV-system comprising an audio component for audio transmission and a video component for video transmission. The AV-system is configured for providing a video-feed from the location. The AV-system is configured to connect to a unified communication cloud server for enabling/performing cloud communication service. The system comprising a functionality service software embedded in the AV-system. The functionality service software being configured for controlling a number of functionalities of the video-feed to generate a processed video-feed. The processed video-feed from the location is configured to be provided to the far-end participant(s) via the cloud communication service.

    Abstract: An audio communication system is disclosed. The audio communication system comprises a speaker device having at least one speaker, a first wireless communication unit and a first connector part; a dongle having control functionality, a second wireless communication unit, and a second connector part, the dangle being configured to operate in a first mode being an audio communication system pairing mode and in a second mode being an audio communication system operating mode. The second connector part is in the audio communication system pairing mode configured to interconnect with the first connector part to enable pairing of the dongle and the speaker device. The second connector part is the audio communication system operating mode configured to interconnect with an external device, providing wireless communication between the speaker device and the external device.
