Focusing on a portion of an audio scene for an audio signal

An apparatus comprising:

• at least one processor;
• and memory having computer executable instructions stored thereon, that when executed, cause the apparatus to:
• obtain a single-channel or multi-channel input audio signal having a plurality of audio sources;
• generate a single-channel or multi-channel output audio signal including the plurality of audio sources spatialized in a sound field;
• obtain 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
• expand 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, move 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, maintain the sound source centered in the indicated at least one direction of spatial attention in the modified sound field.

A method comprising:

• obtaining a single-channel or multi-channel input audio signal having a plurality of audio sources;
• generating 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 control led in gut 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 each sound source in the first region, modifying in the modified sound field an azimuth angle between the sound source and the indicated at least one direction of spatial attention according to a re-mapping function having a non-zero derivative at the indicated at least one direction of spatial attention.
