Show HN: Music Generation - 100x Speed Demo

At the core, we’ve been training music foundation models that are high quality, diverse, controllable, and an order of magnitude faster than anything done before. This required a ton of deep investment across the whole stack from compact representations to architectures to deployment infra. The result is fast enough to enable totally new workflows for this stuff.

The primary input is to capture/upload a photo or video with optional personalization, then the app will generate original lyrics and music based on the context. The next time you see your dog or kid do something funny, you can turn that into a vibe in seconds. We’ve been having a blast creating music in moments that we never would have before.

The most remarkable part is the editing, as sampled in the web demo. In the edit view, you can go deep adding multiple prompts on a timeline and controlling their strengths and interactions. You can mix genres into something totally new or make transitions like going from an operatic aria to death metal. The near-real time editing flow is something that to me feels totally new, like trying GarageBand when it first came out.

There’s a ton more we’re excited to launch in the coming weeks as we work to create more musicians in the world. Excited to hear what you all create!
