1. A processor device for processing an incoming audio stream, the processor device being arranged to be incorporated in an audio system comprising a plurality of pieces of equipment incorporating audio playback devices, each comprising a loudspeaker, the audio playback devices being arranged to form a plurality of playback channels, and the processor device comprising:
a configuration element arranged to acquire input parameters comprising both first characteristics of the incoming audio stream and also second characteristics of the audio playback devices, and to produce configuration parameters on the basis of the input parameters;
a master element arranged to acquire the incoming audio stream together with the configuration parameters, to define processing sequences from the configuration parameters, each processing sequence being associated with and adapted to a respective playback channel, to apply the processing sequences to the incoming audio stream so as to produce processed audio streams, each adapted to a respective one of the playback channels and defining spatialization, and to transmit to each piece of equipment comprising an audio playback device the processed audio stream that is adapted to the playback channel associated with said audio playback device,
wherein configuring each processed audio stream consists of:
transmitting the processed audio stream in dual channel mode, the processed audio stream being in a format in which the dual channel mode is available; or
transmitting the processed audio stream in stereo mode, with two channels conveying a same audio signal.
