Under the hood: Text → transformer prompt conditioning Generation → text-conditioned diffusion transformer in compressed acoustic latent space Output → semantic-acoustic autoencoder decodes a 44.1 kHz stereo waveform Flow matching, teacher–student distillation, and post-training with human feedback reduce the generation path to a few high-quality steps. 💬 1 🔄 0 ❤️ 0 👀 148 📊 1 ⚡
