Time Signature Detection by Using a Multi Resolution Audio Similarity Matrix
Document Type Conference Paper
Audio Engineering Society Convention Paper presented at the 122nd. Convention 2007, May 5-8, Vienna, Austria.
Abstract
A method that estimates the time signature of a piece of music is presented. The approach exploits the repetitative structure of most music, where the same musical bar is repeated in different parts of a piece. The method utilised a multi-resolution audio similarity matrix approach, which allows comparisons between longer audio segments (bars) by combining comparisons of shorter segments (fraction of a note). The time signature method only depends on musical structure, and does not depend on the presence of percussive instruments or strong musical accents.
