The Cadenza ICASSP 2024 Grand Challenge

The Cadenza project aims to enhance the audio quality of music for individuals with hearing loss. As part of this, the project is organizing the ICASSP SP Cadenza Challenge: Music Demixing/Remixing for Hearing Aids. The challenge can be tackled by decomposing the music at the hearing aid microphones into vocals, bass, drums, and other components. These can then be intelligently remixed in a personalized manner to improve audio quality. Alternatively, an end-to-end approach could be used. Processes need to consider the music itself, the gain applied to each component, and the listener's hearing loss. The submitted entries will be evaluated using the intrusive objective metric, the Hearing Aid Audio Quality Index (HAAQI). This paper outlines the challenge.
