Abstract: Examples of the disclosure relate to apparatus, methods and computer programs for controlling amplification and/or attenuation of sound sources based on their position relative to an electronic device. The apparatus includes circuitry for obtaining audio signals from a plurality of microphones of an electronic device and determining loudness of sound sources based on the audio signals so as to determine the loudest sound source. The apparatus also includes circuitry for determining whether the loudest sound source is within a region of interest based on the audio signals and controlling audibility of the sound sources in accordance with whether the loudest sound source is within a region of interest. The audibility of the sound sources is controlled so that if the loudest sound source is not within the region of interest the loudest sound source is de-emphasized relative to other sound sources within the region of interest.

Abstract: An apparatus including circuitry configured to: provide a plurality of metrics associated with multiple directions, wherein the metrics are dependent, for the respective multiple directions, on an amount of direct-sound propagated; accumulate, for the respective multiple directions, values dependent upon the metrics associated with the respective multiple directions to enable determination of sound source directions.

Abstract: A method is provided that includes obtaining two or more microphone audio signals; analysing the two or more microphone audio signals for a defined noise type; and processing the two or more microphone audio signals based on the analysis to generate at least one audio signal suitable for automatic speech recognition. A corresponding apparatus is also provided.
