AnClaS3: A Blackboard-Based Cooperative Framework for Sound Separation

Blackboard modelling provides a great flexibility in structuring complex problems and a robust adaptation to the conditions of the signal to be analyzed, adding both bottom-up and top-down capabilities to the system. AnClaS3 (Analysis, Classification and Synthesis for Sound Separation) is a cooperative project where five research groups collaborate integrating algorithms and developing new separation methods. This contribution defines a blackboard-based framework where four blackboard-based systems interact to integrate the expertise of independent research groups in order to solve a sound separation problem.
