    Abstract: Examples of the disclosure relate to apparatus, methods and computer programs for audio focusing in mobile devices. In some examples the apparatus includes circuitry for providing a plurality of beams for processing microphone audio signals. The apparatus can also include circuitry for analysing the plurality of beams to determine one or more parameter values based on the microphone audio signals in a plurality of different frequency bands, and selecting at least one of the plurality of beams for use based on the determined one or more parameter values in the plurality of different frequency bands such that different beams can be selected for different frequency bands.

    Abstract: Example embodiments relate to conference calls. In a method, there may be provided audio data and associated classification data from a plurality of user devices as part of a conference call, the plurality of user devices including at least a first user device and a second user device. The classification data may be indicative of one of a plurality of predetermined sound types represented by the associated audio data in a current time frame. The method may comprise determining that the audio data provided by the first user device is associated with a dominant speaker. The method may comprise controlling transmission of the audio data as part of the conference call, including preventing transmission of audio data provided by at least the second user device based on its associated classification data being indicative of a restricted sound type and the first user device being associated with a dominant speaker.
