KVAE-Audio is a continuous, full-band (48 kHz) audio autoencoder. It compresses raw waveforms into compact continuous latents and reconstructs them with high fidelity across speech, music, and general sound. The model is designed not only for faithful reconstruction, but as a latent space for generative models — in our internal text-to-audio pipeline, swapping the autoencoder for KVAE-Audio improves generation quality under a fixed generator.

Generative quality is established under a fixed generator — same DiT architecture, training data, and number of steps — varying only the autoencoder. We report objective generation metrics and blind human side-by-side below.

Reconstruction is evaluated on open datasets across domains (the released weights directly substantiate these numbers). Baselines: MMAudio 44.1 kHz VAE, DACVAE from MovieGen Audio, SAME-L (Stable Audio 3 VAE).
