Résumé

Une technique pratique pour réaliser la transformation avec zoom nécessite l’enregistrement d’un signal de longue durée, pour ensuite le transposer en parties en utilisant une plus petite transformation. La possibilité de traiter des signaux de longue durée accroît 1’intérêt de cette technique pour les spécialistes de l'acoustique et des vibrations. Des exemples ainsi qu'une liste imprimée d'un programme informatique sont donnés pour illustrer cette technique.
