Title

Apparatus and method for scaling of ducking gains for spatial, immersive, single- or multi-channel reproduction layouts

Abstract
An apparatus for generating one or more audio output channels from one or more audio signals is provided. The apparatus comprises a gain determiner (110) configured to generate or to receive gain information, wherein the gain information indicates for each audio signal of at least one audio signal of the one or more audio signals how to attenuate or how to amplify said audio signal depending on a position associated with said audio signal and a reference position. Moreover, the apparatus comprises a signal generator (120) configured to generate the one or more audio output channels from the one or more audio signals by attenuating or amplifying at least one of the one or more audio signals depending on the gain information.
