Abstract

The invention refers to a method of automatic recognition of musical compositions and sound signals, which is used for the identification of musical compositions and sound signals played by radio or TV, or performed in public places.According to this invention there is a selection of a desirably large number of musical compositions and sound signals, which we want to identify. For easy reference we will refer to these compositions and signals with the term model signals. In every one of these signals an original procedure is applied leading to the extraction of a set of characteristics which will finally represent each model signal. Subsequently, for the implementation of the recognition, the unknown musical composition or sound signal is received and digitised. To its digitised version the same procedure of extracting a corresponding set of characteristis is applied. These characteristics are compared with the corresponding sets of characteristics of the model signals and with original criteria it is decided if there is a model signal that corresponds to the unknown signal under consideration. Moreover, it is decided which model signal exactly corresponds to the unknown one.As basic uses of the presented invention we may refer the automatic recognition and recording of the programs of radio and TV stations aiming the protection of the literary property, the conducting of statistical researches based on the recognition of musical compositions and sound signals, the verification of the projection of programmed advertisements in radio and TV stations.
