Abstract

Music Information Retrieval (MIR) is a highly-interdisciplinary field bridging the domains of digital audio signal processing and machine learning. Simply put, MIR algorithms allow a computer to “listen” and “understand” audio, such as MP3s in a personal music collection, live streaming audio, or gigabytes of sound effects. In the same way that listeners can recognize a song’s characteristics – tempo, key, chord progressions, genre, or song structure – MIR algorithms are capable of recognizing and extracting this information. By understanding the characteristics of an audio selection, we can perform extensive sorting, searching, music recommendation, metadata generation, and transcription of that audio.

This workshop will target students, researchers, and industry audio engineers who are unfamiliar with the field of Music Information Retrieval (MIR). We will demonstrate the myriad of exciting technologies enabled by the fusion of basic signal processing techniques with machine learning and pattern recognition. The presentations will be applied, multimedia-rich, overview of the building blocks of modern MIR systems. Our goal is to make highly-interdisciplinary technologies and dauntingly-complex algorithms approachable.

The workshop will consist of half-day lectures, half-day supervised lab sessions, and classroom exercises and discussions.

Labs will allow students to design basic ground-up "intelligent audio" systems, use existing MIR toolboxes, applications, and complex systems.

Knowledge of basic digital audio principles, and familiarity with basic programming (Matlab) will be useful. Students are highly encouraged to bring their own audio source material for course demos.
