Abstract

L'invention concerne un procédé et un dispositif qui permettent de déterminer l'introduction et/ou la conclusion d'un article de contenu audio où l'emplacement (EOI<SUB>BS</SUB>; SOO<SUB>BS</SUB>) dans lequel la force de battement de l'article de contenu audio se maintient au-dessus d'un premier niveau seuil pendant un intervalle de temps minimum, et l'emplacement (EOI<SUB>LVL</SUB>; SOO<SUB>LVL</SUB>) dans lequel le niveau de signal de l'article de contenu audio s'est maintenu au-dessus d'un second niveau seuil pendant un intervalle de temps minimum, sont utilisés pour identifier la fin de l'introduction (EOI) et/ou le début de la conclusion (SOO).
