1. A method for processing an audio signal comprising at least ana plurality of audio objects, the method comprising:
determining a panning coefficient for each audio object in relation to a coverage zone, the coverage zone being defined by a plurality of endpoints distributed in a sound field;
determining one or more submixes of the audio signal, wherein each submix corresponds to a different coverage zone;
determining a submix gain for each submix;
determining an object gain for rendering each audio object, wherein the object gain is generated for each audio object based on the submix gain and the corresponding panning coefficient; and
rendering each audio object based on the corresponding object gain.
