Harmonai

What Harmonai is

Harmonai is an open source audio laboratory owned by Stability AI. Its aim stated on the site is making music creation more accessible and enjoyable through open generative audio tools. The core release is Dance Diffusion, a diffusion-based system that can generate audio from scratch, re-create uploaded samples or interpolate between different pieces, with several trained models available to try.

What you can do with it

• Generate loop material from nothing
• Feed a sample and get reworked variations
• Interpolate between two audio pieces
• Try several published models
• Study open generative audio code

Who it is for

• Developers comfortable running models locally
• Sound designers experimenting with diffusion audio
• Researchers comparing open models

What to watch out for

• Open research releases carry licence terms that often exclude commercial use; read them before publishing anything
• Uploading samples you do not own to a re-creation model creates rights problems
• Output length and fidelity lag commercial tools
• Local execution requires capable hardware
