1. A method of rendering an audio signal, received from a content authoring device, for playback in an audio environment defined by a target loudspeaker system, the audio signal including object audio data relating to an audio object, associated object position data indicative of a position of the audio object at a given point in time, and object rendering control data indicative of a position modification to be applied, at the given point in time, to the audio object in the audio environment, the method comprising:
receiving the object audio data relating to the audio object;
receiving loudspeaker layout data for the target loudspeaker system;
receiving the object rendering control data indicative of a position modification to be applied, at the given point in time, to the audio object in the audio environment; and
rendering the audio object, at the given point in time, in response to the position of the audio object at the given point in time, the loudspeaker layout data, and the object rendering control data, to output the audio object, at the given point in time, at a modified object position, wherein the object rendering control data determines a degree of position modification to be applied, at the given point in time, to the audio object during the rendering of the audio signal, wherein the object position data relates to coordinates in the audio environment.
