Abstract: A distributed system and a corresponding data processing method are disclosed, for decomposing audio signals including mixed audio sources. The system comprises at least one client terminal, a remote queuing module and at least one remote audio data processing module connected in a network. A client terminal stores source audio signal data, selects at least one signal decomposition type, uploads source audio signal data with data representative of the decomposition type selection to the queuing module, and downloads decomposed audio signal data. The queuing module queues uploaded source audio data and distributes same to data processing module(s). The queuing module also queues uploaded decomposed audio signal data and distributes same to client terminal(s). An audio data processing module processes distributed source audio data into decomposed audio signal data according to the type selection, and uploads decomposed audio signal data to the at least one remote queuing resource.
