FdAudio: One-Step Text-to-Audio Generation with Fréchet-Distance Post-Training

Jul 14, 2026

Researchers introduce FdAudio, a post-training method that enhances one-step text-to-audio generation by optimizing a Fréchet-distance loss across embedding spaces. FdAudio achieves an 11.4% reduction in FD score and a 28.8% improvement in FAD compared to the MeanAudio baseline, while also preserving high-fidelity multi-step synthesis through a MeanFlow consistency anchor.

Why it matters: FdAudio narrows the quality gap between one-step and multi-step text-to-audio generation, enabling faster synthesis without compromising audio fidelity.
