Lecturer in Audio Signal Processing
School of Electronic Engineering and Computer Science
Queen Mary University of London
Queen Mary University of London
Research
music information retrieval, machine learning for audio, audio signal processing, binaural audio
Interests
Johan’s aim is to make machines understand music to the level of a trained professional, such that new tools can be developed to assist musicians performing live or in the studio, listeners navigating large music collections and learners studying music. To that end, he uses a combination of machine learning, signal processing, data science and music theory. In recent years, he has been working on narrowing the gap between academic research and user-centric applications, web-based music services and the personalisation of spatial and immersive audio.Publications
