Abstract:
Apparatus comprising one or more processors configured to: receive at least two microphone audio signals (101) for audio signal processing wherein the audio signal processing comprises at least a spatial audio signal processing (303) and beamforming processing (305); determine spatial information (304) based on the audio signal processing associated with the at least two microphone audio signals; determine focus information (308) for the beamforming processing associated with the at least two microphone audio signals; and apply a spatial filter (307) in order to synthesize at least one spatially processed audio signal (312) based on the at least one beamformed audio signal from the at least two microphone audio signals (101), the spatial information (304) and the focus information (308) in such a way that the spatial filter (307), the at least one beamformed audio signal (306), the spatial information (304) and the focus information (308) are configured to be used to spatially synthesize (307) the at least one spatially processed audio signal (312).
