Abstract (en)
[origin: WO2010012927A1] The invention relates to a method for processing audio data to reconstruct multi-channel audio data at least from data on a reduced number of channels and from spatialization data. Received spatialization data is tested for validity. If the test is positive, a spatialization value is predicted in accordance with a respective model from a plurality of models. A prediction model is selected from the thus-predicted spatialization values and from the received spatialization data so as to enable, if defective spatialization data is later received, the prediction according to said selected model of a spatialization value and the use of said predicted spatialization value to reconstruct multi-channel audio data.
