Technical Innovation
1 Latent Diffusion Approach
Utilizes a non-autoregressive structure for parallel audio content generation, significantly faster than language model-based methods.
2 Two-Stage Architecture
Combines a Variational Autoencoder (VAE) for compact latent representations and a Diffusion Transformer (DiT) for song generation through iterative denoising.
3 Lyrics Alignment
Novel mechanism ensures semantic correspondence between lyrics and vocals, maintaining high intelligibility in the final output.
