metamidi: a tool for automatic metadata extraction from MIDI files

Abstract

The increasing availability of on-line music has motivated a growing interest for organizing, commercializing, and delivering this kind of multimedia content. For it, the use of metadata is of utmost importance. Metadata permit organization, indexing, and retrieval of music contents. They are, therefore, a subject of research both from the design and automatic extraction approaches. The present work focuses on this second issue, providing an open source tool for metadata extraction from standard MIDI files. The tool is presented, the utilized metadata are explained, and some applications and experiments are described as examples of its capabilities.
