Summary
| Description |
Demonstration of an algorithmically-generated audio track featuring 1980s synthesiser pop music, created using Riffusion, an open-source fine-tuned derivative of the Stable Diffusion image-generation diffusion model that has been retrained to generate images of audio spectrograms, which can then be converted into audio files. An audio spectrogram is a visual representation of an audio clip's frequency content, and images of spectrograms can be converted into audio via short-time Fourier transform, using the Griffin-Lim algorithm to approximate phase during audio reconstruction. While the Stable Diffusion AI model is originally intended to generate visual images from a textual prompt, Riffusion has been retrained from Stable Diffusion v1.5 to instead generate spectrogram images from text prompts describing musical motifs, fine-tuned through the use of Nvidia A10G enterprise datacenter GPUs.
The spectrograms were generated using the Riffusion Inference Server running the riffusion-model-v1 diffusion model, paired with the Riffusion App UI frontend. The following values were used:
This resulted in the output spectrogram image:  Spectrograms were then converted to WAV audio using this python script: |
