Abstract:
An apparatus (303) comprising means configured to: obtain at least one audio signal (112); determine at least one direction parameter (506) of at least one propagating sound associated with the at least one audio signal (112); determine at least one direction (302) of at least one sound source associated with the at least one audio signal (112); modify the at least one direction parameter (506) in accordance with the determined at least one direction (302); and output the modified at least one direction parameter (508).
