    Abstract: Examples of the disclosure relate to apparatus, methods and computer programs for processing spatial audio to reduce the effects of errors within the spatial audio. The apparatus can be configured to obtain spatial audio and associated one or more three-dimensional parameters wherein the one or more three-dimensional parameters comprise one or more direction parameters. The apparatus can also be configured to determine one or more ranges for direction parameters when the one or more three-dimensional parameters are reduced to two dimensions to obtain one or more two-dimensional parameters. The apparatus can also be configured to apply processing to the one or more two-dimensional parameters based on whether or not the one or more ranges in two dimensions are in accordance with one or more criteria.

    Abstract: An apparatus for providing directional audio capture may include a processor and memory storing executable computer program code that cause the apparatus to at least perform operations including assigning at least one beam direction, among a plurality of beam directions, in which to direct directionality of an output signal of one or more microphones. The computer program code may further cause the apparatus to divide microphone signals of the microphones into selected frequency subbands wherein an analysis performed. The computer program code may further cause the apparatus to select at least one set of microphones of the apparatus for selected frequency subbands. The computer program code may further cause the apparatus to optimize the assigned at least one beam direction by adjusting a beamformer parameter(s) based on the selected set of microphones and at least one of the selected frequency subbands. Corresponding methods and computer program products are also provided.
