Abstract:
1. A method comprising; receiving at least two audio signals based on acoustic energy captured from a target audio source by a portable electronic apparatus; determining a change in one or more of position and orientation of the apparatus; and processing the at least two audio signals dependent on the change in one or more of position and orientation to generate at least two output signals comprising a representation of acoustic energy from the direction of the target audio source; wherein determining change in one or more of position and orientation of the apparatus comprises determining the change in one or more of position and orientation from a first time period to a second time period using a camera; wherein determining the change in one or more of position and orientation of the apparatus using the camera comprises: detecting an object of interest in a first image in the first time period; and detecting a displacement of the object of interest in a later image in the second time period so as to track the object associated with the target audio source.
