Patent ID: 7356465

Claim:
A computer device comprising: A memory ( 8 , 108 ), capable of storing audio signals ( 14 , 114 ) in part pre-recorded, each corresponding to a source defined by spatial position data ( 16 , 116 ), and a processing module ( 10 , 110 ) to process these signals in real time as a function of the spatial position data, characterised in that the processing module ( 110 ) is capable of calculating instantaneous power level parameters on the basis of the audio signals ( 14 ), the corresponding sources being defined by said parameters of the instantaneous power level, in that the processing module ( 110 ) comprises a selection module ( 120 ) capable of grouping together certain of the audio signals into a variable number of audio signal groups, and that the processing module ( 110 ) is capable of calculating representative spatial position data of a group of audio signals as a function of the spatial position data ( 116 ) and the parameters of the instantaneous power levels of each corresponding source in order to obtain a mixing signal which is audible to a listener.
