Abstract
Das Gebiet Audio-Retrieval kann grob in drei Bereiche unterteilt werden: Musik-Retrieval, Retrieval gesprochener Sprache und Retrieval akustischer Ereignisse. Alle drei Bereiche gehen i. d. R. vom Audiosignal als Quelle aus, welches über eine Signalanalyse, meist eine Spektralanalyse über eine Fouriertransformation, weiterverarbeitet und in eine für das Retrieval geeignete Beschreibung gebracht wird. Dabei gibt es auch alternative Ansätze, wie z. B. die Nutzung der hier nicht diskutierten MIDI-Codierung im Musik-Retrieval, die ohne ein akustisches Signal auskommt und bereits eine für das Retrieval geeignete Form der Kodierung als Grundlage hat.
