1. A method for generating audio content for an object based audio program, said method comprising:
generating conditional rendering metadata corresponding to at least one object channel, wherein the conditional rendering metadata is indicative of at least one rendering constraint for the at least one object channel, wherein the rendering constraint is related to a playback speaker array configuration;
generating size metadata associated with the at least one object channel;
determining a set of audio channels including the at least one object channel based on the conditional rendering metadata; and
generating the object based audio program such that said object based audio program is indicative of the set of audio channels, the conditional rendering metadata and the size metadata;
wherein the rendering constraint includes a constraint relating to an elevation of at least a speaker in the playback speaker array configuration, wherein the at least a speaker in the playback speaker array configuration has an assumed location based on the rendering constraint of the conditional rendering metadata, and wherein the object based audio program is an encoded bitstream comprising frames.
