1. An audio processing device comprising:
- at least one connector that receives data defining an input sound signal corresponding to a plurality of audio channels;
a processing module that determines at least one signal intended for a loudspeaker as a function of said defining data, anda detection module that detects the proximity of another audio processing device, wherein the processing module is capable of determining said signal intended for the loudspeaker as a function of a number of other detected device(s); and
wherein said determining of the signal by the processing module comprises;
i selecting a channel from a plurality of audio channels corresponding to the defining data of the input sound signal as a function of an absolute distance between the device and another detected device compared to a distance threshold;
ii combining different audio channels from a plurality of channels corresponding to the defining data of the input sound signal as a function of an absolute distance between the device and another detected device compared to a distance threshold; and
iii selecting frequencies of a combination of different audio channels from a plurality of channels corresponding to the defining data of the input sound signal as a function of an absolute distance between the device and another detected device compared to a distance threshold,and wherein the audio processing device further comprises an audio retrieval system comprising one or more loudspeakers, each loudspeaker capable of receiving and restoring the determined signal for said loudspeaker by said processing module.

Abstract
The invention relates to an audio processing device (1) including:
- at least one connector (2, 7), suitable for receiving data defining an input sound signal;
- a processing module (5, 6) suitable for determining at least one signal intended for a loudspeaker (12, 13) as a function of said defining data,
- a communication module (8, 9) for communicating with at least one other audio processing device, according to claim 1;
said device being characterized in that it furthermore includes a detection module (4) suitable for detecting the proximity of another device according to claim 1 and in that the processing module is suitable for determining said signal intended for the loudspeaker as a function furthermore of a number of other detected device(s).
