Abstract

Der interaktive Musik-Abspieler ereint die Audio-Wiedergabe, die Signal-Analyse und die Signal-Transformation mittels Effekten und Loops. Die Erfindung ermöglicht sowohl eine Echtzeit-Erkennung des Tempos (A) und der Phase (P) eines Audiotracks, als auch deren automatische Angleichung. Zusätzlich liefert die Analyse die notwendigen Ausgangsdaten für die Steuerung temposynchroner Effekte und Loops. Vorteile sind unter anderem die dadurch geschaffene Möglichkeit der Automatisierung des sog. Beatmatchings und des gesamten Mix-Vorgangs, wobei letzterer anhand von entsprechend generierten digitalen Steuerdaten für u.a. die Stellglieder des Musik-Abspielers abspeicherbar ist. Dadurch sind der Vorgang und das Ergebnis unabhängig von den physischen Audiodaten nichtdestruktiv reproduzierbar, was mögliche urheberrechtliche Probleme bei der Weitergabe von durch einen Mix-Vorgang geschaffenen neuen Gesamtwerken von einer Mehrzahl von Musikstücken vermeidet.
