Patent ID: 8357847

Claim:
Method for the automatic or semi-automatic composition, of a multimedia sequence including a prior phase including the creation of a reference structure of a multimedia sequence and the breakdown of said structure into a limited numbers of basic components assimilated to tracks, each of these basic components associated with a set of basic subcomponents (or bricks) which comprises at least musical movements, harmonies or styles and an automatic composition phase of a new multimedia sequence containing a choice of subcomponents, wherein said prior phase comprises the assigning of psychoacoustic descriptors or attributes to each of the subcomponents and the storage of subcomponents and descriptors or attributes that are assigned to them in databases and said automatic composition phase comprises a generation on the basic components of a sequence of subcomponents with a chaining characterised by a maintaining or a replacing of the subcomponents said chaining being calculated according to an algorithm that determines, for each subcomponent a selection criterion taking into account its psychoacoustic descriptors or attributes and context parameters, said composition phase repeating through looping, each sequence of subcomponents regenerating itself permanently at a hearing rhythm by associating a subcomponent to each basic component, the listener being able to intervene during said composition phase on the choice of subsequent subcomponents by influencing the operation of above-mentioned algorithm.
