Tonal Description of Polyphonic Audio for Music Content Processing

Emilia Gómez, Perfecto Herrera
Universitat Pompeu Fabra, Barcelona, Spain

The purpose of this paper is to describe a system that automatically extracts metadata from polyphonic audio signals. This metadata describes the tonal aspects of music. We use a set of features to estimate the key of the piece and to represent its tonal structure, but they could also be used to measure the tonal similarity between two songs and to perform some key-based segmentation or establish a tonal structure of a piece.
