Abstract

Die Erkenntnis der vorliegenden Erfindung besteht darin, dass die Melodieextraktion oder automatische Transkription deutlich stabiler und gegebenenfalls sogar unaufwendiger gestaltet werden kann, wenn die Annahme genügend Berücksichtigung findet, dass die Hauptmelodie derjenige Anteil eines Musikstückes ist, den der Mensch am lautesten und prägnantesten wahrnimmt. Dies aufgreifend wird gemäß der vorliegenden Erfindung die Zeit-/Spektraldarstellung bzw. das Spektrogramm eines interessierenden Audiosignals unter Verwendung der Kurven (774) gleicher Lautstärke, die die menschliche Lautstärkewahrnehmung wiederspiegeln, skaliert (772), um auf der Basis der sich ergebenden wahrnehmungsbezogenen Zeit-/Spektraldarstellung die Melodie des Audiosignals zu ermitteln.
