DEMON (Diffusion Engine for Musical Orchestrated Noise), an open-source real-time music diffusion engine.

Technical Positioning

An open-source, real-time music diffusion engine, analogous to StreamDiffusion for audio, enabling near real-time remixing and instrument-like playability of generative music with ACEStep 1.5.

SaaS Insight & Market Implications

DEMON targets the burgeoning generative AI music market, specifically addressing the need for real-time interaction in music creation. By adapting diffusion models from images to audio and optimizing for '25Hz local GPU' performance, it enables musicians to 'play it like an instrument' and 'remix in near real-time.' This capability directly challenges traditional, often post-production-heavy music workflows. The open-source nature, coupled with extensive LoRA/dora releases, fosters community engagement and rapid iteration. While limitations exist (e.g., non-continuous music generation), DEMON represents a significant step towards democratizing advanced AI-driven music production, potentially disrupting existing digital audio workstation (DAW) paradigms and empowering a new generation of real-time audio artists.

Show HN: Demon – open-source real-time music diffusion engine, 25Hz local GPU

YO,I’m Ryan, lead author. I’ve been contributing open source generative audio stuff for a while now, audio reactive Comfy nodes, extended ACEstep support in Comfy, etc.. I just opened-sourced a new audio project that I've been working on for a few months and I want to tell y'all about it.WHAT IS IS
DEMON: Diffusion Engine for Musical Orchestrated NoiseThis is StreamDiffusion but with audio instead of images, and ACEStep 1.5 instead of Stable Diffusion. It’s responsive enough that you can play it like an instrument, and remix in near real-time.I also distilled the ACEStep VAE: it’s faster at the expense of some quality.I also trained something like 200 lora/dora for ACEStep 1.5 and 1.5XL: I will release these in batches of 5 or 10 or somethingWHY IT IS
Two reasons:
1) Making music is an inherently real-time activity
2) Why not broSOME RUNTIME CAPABILITIES
-Real-time remixing of songs
-Denoise, structure, timbre strength adjustment
-Reference track swapping
-Prompt blending, parameter scheduling with curves
-LoRA hotswapping, runtime strength adjustment
-Latent channel (research preview)
-Feedback
-Vocal stem cutting/pasting with melformer (s/o u/BuffMcBigHuge)
-XL support (its less stable, working out VRAM pressure issues and whatnot)
-Lyrics/vocals SOON
-Spectral quality SOON
-Other stuffSOME LIMITATIONS
-ACEStep (correctly) ‘begins’ and ‘ends’ the song. This system is optimized for remixing either an entire song, or continuously remixing a loop. The loop works fine, but this is not pure, continuous music. Autogression wins here.
-Many others, for a more exhaustive list, please see the full writeup via the project page
-Please let us know if you find any, I would love to try and address them if possibleLINKS

Mind blown! This is absolutely sick.

byMARCO • May 27, 2026

Wow this is so cool! Do we have VST support?

hthillman • May 27, 2026

can you explain performance differences vs Magenta / Lyria? that's the most similar thing I can think of

viborcip • May 27, 2026

this is sick and why not bro!!what was the biggest unexpected unlock you got while building this? like was there something that just worked out unexpectedly easy compared to the rest?also, another question, how much time it took you to build this thing all together?

incredible piece of work

Let's talk more about why it is reason number 2.
