Unsupervised vocal dereverberation with diffusion-based generative models

Saito, Koichi, Murata, Naoki, Uesaka, Toshimitsu et al.

Understand

Removing reverb from reverberant music is a necessary technique to clean up audio for downstream music manipulations.

  • Reverberation of music contains two categories, natural reverb, and artificial reverb.
  • Artificial reverb has a wider diversity than natural reverb due to its various parameter setups and reverberation types.
  • However, recent supervised dereverberation methods may fail because they rely on sufficiently diverse and numerous pairs of reverberant observations and retrieved data for training in order to be generalizable to unseen observations during inference.
