Research Fellow

Profile

Dr Derry FitzGerald is a  Post-Doctoral Researcher in CIT Cork School of Music. He was a Stokes Lecturer in Sound Source Separation algorithms at the Audio Research Group in DIT from 2008-2013. Previous to this he worked as a post-doctoral researcher in the Dept. of Electronic Engineering at Cork Institute of Technology, having previously completed a Ph.D. and an M.A. at Dublin Institute of Technology. He has also worked as a Chemical Engineer in the pharmaceutical industry for some years.In the field of music and audio, he has worked as a sound engineer and has written scores for theatre. He has recently utilised his sound source separation technologies to create the first ever officially released stereo mixes of several songs for the Beach Boys, including 'Good Vibrations', 'Help me Rhonda' and 'I get around'.His research interests are in the areas of automatic music transcription, sound source separation, tensor factorizations, and music information retrieval systems.
 

Research Interests

His research interests are in the areas of sound source separation, upmixing from mono to stereo or 5.1 surround sound, automatic music transcription, non-negative matrix and tensor factorizations, and music information retrieval systems.
