About the model: Riffusion is a latent text-to-image diffusion model capable of generating spectrogram images given any text input. These spectrograms can be converted into audio clips.
<br />—
<br />The Riffusion model was created by fine-tuning the Stable-Diffusion-v1-5 checkpoint.
<br />—
<br />The model is intended for research purposes only. Possible research areas and tasks include
generation of artworks, audio, and use in creative processes, applications in educational or creative tools, research on generative models.
