Abstract

L'amélioration d'une entrée audio comprend les étapes consistant à : recevoir un paramètre de limitation associé à l'entrée audio ; et à déterminer une entrée audio limitée. Une autre piste de l'entrée audio est manipulée sur la base de la piste de l'entrée audio limitée. Puis les pistes audio sont combinées. La présente invention concerne également l'adaptation d'une entrée audio à une clé musicale. L'intervalle entre deux notes de l'entrée audio est déterminé. Une note correspondant à la seconde note est sélectionnée sur la base d'une clé musicale et de l'intervalle. Les intervalles entre chaque paire de notes de l'entrée audio sont additionnés. Chaque note est évaluée. La note présentant la meilleure correspondance est sélectionnée. La seconde note de l'entrée audio est adaptée à la fréquence de la note présentant la meilleure correspondance. Une création de pistes d'harmonisation comprend une étape consistant à recevoir l'entrée audio. Puis les pistes d'harmonisation sont créées. Chacune des pistes d'harmonisation est transposée. Les notes individuelles sont manipulées sur la base d'un seuil de rigueur d'accord. Puis une sortie audio est délivrée.
