Classification: CPC H  G | IPC G  H

Claim 18:
19. An apparatus, the apparatus comprising:
memory; and
processing circuitry comprising a processor, wherein the apparatus is configured to perform a method comprising:
obtaining a distance value representing a distance between a listener and the audio source;
based on the distance value, selecting from among a set of two or more gain functions a particular one of the two or more gain functions;
evaluating the selected gain function using the obtained distance value to obtain a gain value to which the obtained distance value is mapped by the selected gain function; and
providing the obtained gain value to an audio source renderer configured to render the audio source using the obtained gain value and/or rendering the audio source using the obtained gain value, wherein
the set of gain functions comprises at least a first gain function and a second gain function, and
selecting a particular one of the two or more gain functions based on the distance value comprises comparing the distance value to a first threshold and selecting a particular one of the two or more gain functions based at least in part on the comparison,
the audio source has an associated length (L), and
the first threshold is a function of the associated length.
