The Stable Audio demo showcases a model that can generate variable-length and long-form stereo music at 44.1kHz, as well as sound effects. The model can produce high-quality audio, but some listeners note that the music sounds unnatural or 'off' in certain ways. The demo includes comparisons with state-of-the-art models and examples of autoencoder reconstructions. The model's capabilities are demonstrated through various prompts and audio examples.
