Welcome
This is my homepage at CCRMA. I was here as visiting researcher during the academic year 2009-2010.
During that time, I worked closely with Jonathan Abel and
Gautham Mysore. This resulted in a couple of conference papers on source separation with the PLCA
algorithm using
synthesized music scores as prior data.
Nowadays, I'm back at the VisionLab of the Physics department at the
University of Antwerp, and continue my Ph.D research on how information
from symbolic music data can be used to improve analysis of audio signals. My webpage there also contains a list of publications.
This paper describes the basic design of a system for source separation of single channel music audio files,
using its music score as prior information to guide the separation.
Download the paper here. For more details and example soundfiles,
there is a separate page with more information.
This paper presents a thorough evaluation of the performance of the previously proposed system, identifying its
strengths and weaknesses with a wide variety of parameters and input data. Large-scale
measurements using objective criteria were performed using a comprehensive test database. The database, which
we created ourselves, is made available to the public free of charge and free to use.

More information on the database and links to download it, can be found on this separate page.
