Patent ID: 8509454

Claim:
A method comprising: obtaining a single-channel or multi-channel input audio signal having a plurality of audio sources; generating, with a processor, a single-channel or multi-channel output audio signal including the plurality of audio sources spatialized in a sound field; obtaining at least one parameter from a user controlled input device, the at least one parameter indicating at least one direction of spatial attention in the sound field; and expanding a first region of the sound field around the indicated at least one direction of spatial attention to produce a modified sound field in the output audio signal to a user, wherein the expanding includes: for any sound source in the first region and not centered in the indicated at least one direction of spatial attention in the sound field, moving the sound source in the modified sound field according to a re-mapping function; and for any sound source centered in the indicated at least one direction of spatial attention in the sound field, maintaining the sound source centered in the indicated at least one direction of spatial attention in the modified sound field.
