Audio Quality Enhancement

via “diffusion-based audio enhancement with multiband diffusion”

Meta's library for music and audio generation.

Unique: Applies diffusion-based refinement independently to frequency bands, enabling targeted enhancement of specific spectral regions while maintaining overall audio structure. Operates as a post-processing stage compatible with any audio source, not just AudioCraft-generated content.

vs others: More effective at artifact reduction than traditional filtering; enables quality improvements without model retraining. Slower than alternatives but produces higher perceptual quality.
