S. Koyama's Lab

Welcome to Audio Processing Research Group at National Institute of Informatics, Tokyo, Japan! This group led by Prof. Shoichi Koyama was created in 2023.

Our principal research interests are signal processing and machine learning in audio and acoustics. In particular, we develop methodologies for analysis and control of acoustic fields with their applications to virtual/augmented reality audio, noise control, acoustic imaging, and others.

Join our group if interested in our research!
