Abstract
An ad-hoc Adaptive Wireless Mobile Sound System comprises mobile phone nodes and a Master device for sending a query to the nodes, to verify whether they hold in their memory a specific song/track and to learn their music playing capabilities, for conveying to the nodes that do not have a specific file in their memory, a compressed audio stream of the file, for selecting, based on an answer to the query, an appropriate surround scheme that considers the mobile nodes capabilities, for publishing the surround scheme by which a playing role is allocated for each of the nodes, and for synchronizing the mobile nodes and to order them to play a stream audio file according to the surround scheme. In one embodiment, the Master is operable to select a compensating surround scheme when one of the nodes is found incapable of executing its allocated role during play time.
