Patent ID: 8634577

Claim:
An audio decoder comprising: effect means for generating modified down-mix audio signals from received down-mix audio signals, said received down-mix audio signals comprising a down-mix of a plurality of audio objects, said modified down-mix audio signals obtained by applying effects to estimated audio signals corresponding to audio objects comprised in said received down-mix audio signals, said estimated audio signals being derived from the received down-mix audio signals based on received parametric data, said received parametric data comprising a plurality of object parameters for each of the plurality of audio objects, said modified down-mix audio signals based on a type of the applied effect being decoded by decoding means or rendered by rendering means or combined with the output of rendering means; the decoding means being arranged for decoding the audio objects from the down-mix audio signals or the modified down-mix audio signals based on the parametric data; the rendering means being arranged for generating at least one output audio signal from the decoded audio objects.
