1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed with the at least one processor, cause the apparatus to:
obtain an object track and an ambience track;
obtain a control value configured to control relative levels of the object track and the ambience track;
estimate a leakage between the object track and the ambience track;
determine at least one leakage level gain control value based on the control value and the leakage; and
apply the at least one leakage level gain control value to at least one of: the object track; or the ambience track, where the application of the at least one leakage level gain control value is such that a rendered audio signal is based on the application of the at least one leakage level gain control value to at least one of: the object track; or the ambience track.
