Empreintes audio et stratégies d'indexation associées pour l'identification audio à grande échelle
N this work we give a precise definition of large scale audio identification. In particular, we make a distinction between exact and approximate matching. In the first case, the goal is to match two signals coming from one same recording with different post-processings. In the second case, the goal is to match two signals that are musically similar. In light of these definitions, we conceive and evaluate different audio-fingerprint models.Dans cet ouvrage, nous dĂ©finissons prĂ©cisĂ©ment ce quâest lâidentification audio Ă grande Ă©chelle. En particulier, nous faisons une distinction entre lâidentification exacte, destinĂ©e Ă rapprocher deux extraits sonores provenant dâun mĂȘme enregistrement, et lâidentification approchĂ©e, qui gĂšre Ă©galement la similaritĂ© musicale entre les signaux. A la lumiĂšre de ces dĂ©finitions, nous concevons et examinons plusieurs modĂšles dâempreinte audio et Ă©valuons leurs performances, tant en identification exacte quâen identificationapprochĂ©e
