| 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. |
