Generated spectrogram from the prompt "bossa nova with electric guitar" (top), and the resulting audio after conversion (bottom)

Riffusion is a neural network, designed by Seth Forsgren and Hayk Martiros, that generates music using images of sound rather than audio.[1] It was created as a fine-tuning of Stable Diffusion, an existing open-source model for generating images from text prompts, on spectrograms.[1] This results in a model which uses text prompts to generate image files, which can be put through an inverse Fourier transform and converted into audio files.[2] While these files are only several seconds long, the model can also use latent space between outputs to interpolate different files together.[1][3] This is accomplished using a functionality of the Stable Diffusion model known as img2img.[4]

The resulting music has been described as "de otro mundo" (otherworldly),[5] although unlikely to replace man-made music.[5] The model was made available on December 15, 2022, with the code also freely available on GitHub.[2] It is one of many models derived from Stable Diffusion.[4]

Riffusion is classified within a subset of AI text-to-music generators. In December 2022, Mubert[6] similarly used Stable Diffusion to turn descriptive text into music loops. In January 2023, Google published a paper on their own text-to-music generator called MusicLM.[7][8]
