Abstract

Die Erfindung betrifft ein Verfahren zum Optimieren eines Audiosignals mit den Schritten eines Kontinuierlichen Bestimmens der Differenz eines vorbestimmten Audiosignals und eines modifizierten Audiosignals, das aus dem vorbestimmten Audiosignal resultiert, wobei die Differenz im Zeitbereich und/oder im Frequenzbereich bestimmt wird, und eines kontinuierlichen Bestimmens eines Optimierten Audiosignals unter Verwendung der Differenz im Zeitbereich und/oder Frequenzbereich.
