Object and Ambience Relative Level Control for Rendering

An apparatus including circuitry configured to: obtain an object track and an ambience track; obtain a control value configured to control the 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 value to at least one of: the object track; and the ambience track, the application of the at least one leakage level gain 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; and the ambience track.
