Abstract: An apparatus comprising: a depth map estimator configured to determine, associated with at least one visual image, a depth map comprising at least one distance value in a direction relative to an apparatus; a direction of arrival estimator configured to determine, using at least two microphones, at least one audio source signal with a direction; and an audio signal processor configured to process the at least one audio source signal based on the at least one distance value in the direction of the at least one audio source signal.

Abstract: An apparatus configured to: determine a viewing angle associated with at least one apparatus camera; determine from at least two audio signals at least one audio source orientation relative to an apparatus; and generate at least one spatial filter including at least a first orientation range associated with the viewing angle and a second orientation range relative to the apparatus.
