Music Mixing Style Transfer: A Contrastive Learning Approach to Disentangle Audio Effects

ICASSP, 2023
Junghyun Koo*, Marco A. Martínez-Ramírez, Wei-Hsiang Liao, Stefan Uhlich*, Kyogu Lee*, Yuki Mitsufuji

We propose an end-to-end music mixing style transfer system that converts the mixing style of an input multitrack to that of a reference song. This is achieved with an encoder pre-trained with a contrastive objective to extract only audio effects related information from a r…
