1. A method in a decoder for decoding an encoded data stream comprising:
receiving a data stream comprising frames of M signals which are combinations of N encoded audio objects, wherein the M signals are based on spatial locations of the N audio objects and on importance values of the N audio objects indicating the importance of the N audio objects in relation to each other,
receiving side information including parameters which allow reconstruction of a set of audio objects based on the N audio objects, the side information including an interpolation duration parameter that is independent of frame length; and
reconstructing the set of audio objects based on the side information, wherein the set of audio objects comprises a plurality of audio objects which are combinations of the N audio objects, and the number of which is lower than N; and
rendering the N audio objects to output channels of a predefined channel configuration, the rendering including interpolating from a current rendering setting to a desired rendering setting in accordance with the interpolation duration parameter.
