Music and Audio Computing Lab

The Music and Audio Computing Lab (MACLab) is a music research group in the Graduate School of Culture Technology at KAIST. Our mission is to improve the way people enjoy, play, and create music through technology. We are particularly interested in "Music AI" that can understand music, represent its meanings in a human-friendly manner, and generate new musical content to assist human creativity. The following are the main research areas and broad research topics that we are working on:

  • Music Informational Retrieval
  • Audio Signal Processing
  • Machine Learning and Deep Learning for Music and Audio
  • Human-AI Interaction for Music
  • Computational Analysis and Modeling of Music Performance
  • Sound Synthesis and Digital Audio Effects
