By my own little comparison in which I've given the same song to both, Demucs appears much better (while requiring an app and consuming far more CPU). Thanks for sharing! I had no idea this was a thing.

demucs works far better than anything else I've used, especially with more esoteric kinds of music in my experience. plus you can run it with GPU support as well!

Demucs is awesome no doubt.

>plus you can run it with GPU support as well!

Open-Unmix also originally runs on the GPU like it was intended for, since it uses PyTorch just like Demucs.

I'm curious about using WASM + WebGPU to add GPU acceleration to this project, though.

For those interested, Facebook's Demucs page ( https://github.com/facebookresearch/demucs ) gives performance comparison for several models including open-unmix. See also: https://www.stemroller.com This runs as a local app on Windows and Mac.

My dream (and next major project) is to get Demucs (v4, Hybrid Transformer) running in WASM, similar to what I've done with Eigen/C++ and Open-Unmix.

Oh yes, that would be amazing! Good luck!

"Runs locally in your browser! Unlike similar products, it’s free to use and doesn’t store your data. All processing is done in your browser, and your files are never uploaded anywhere. It runs well on computers and very slowly on smartphones; user beware." I'm impressed by the fact that this was the choice made. I can only imagine it also helps keep the operational costs down, as well as liability for copyright and…

I'll be honest with you - I wouldn't even know what to do with user data if I collected it. I'm not great at training neural networks or understanding how to augment training with additional data. Basically, the _only_ special thing about freemusicdemixer is that it runs client-side, because I'm better at writing C++ for a pre-trained network than I am at training new neural networks. However, it's a cool advantage s…

It is very nice to be able to compute this in our browsers without limits or registration. The results are not always perfect but already allows having good time testing remixes or doing karaoke with friends! Thanks for sharing your work.

I envisioned my site would be useful for quick and dirty prototyping - especially since the outputs are not licensed for commercial use.

Then, when one's project idea is validated, they could then used a paid stem separation service with higher quality and commercial licensing.

That's why I added some sentences on the website to solicit partnerships for targeted advertisements, to see if any pro demixing companies were interested.

after finally getting some free time to play with this, i did. i've used other non-AI based programs to remove vocals. the in sound is totally different and obviously beyond because they are stems. There's the tell-tale sound that I've heard from all of these generative AI audio things that sounds like a very heavily compressed version of the original. To describe it visually, it looks just like taking an image and removing part of the image and then using a generative fill. Compare how the fill looks to the rest of the image, and that's what this sounds like. Similar, but just smeared and not clean. Maybe it's not noticeable to people that don't work with audio, but it is one of those things that once you're trained to hear it, you can never not hear it.

it is probably the most useful application of the AI things I have seen AND it does as advertised on the box. nice work on the project.

That's an interesting idea. Scratch track stems while we're waiting for the approvals and delivery of final assets.

Maybe I can ask HN out loud how I can start figuring out how to get this website on Google search results - e.g. I want it to show up when I search relevant terms like "free stem separation" "free music separation" "free music isolation" "music stem separation" "music source separation"

Add meta keyword and description tags and detailed text (HTML Tags) to each page you want indexed and post your app page URLs across social media sites, then give it a little time, indexing, especially among lots of competition won't happen instantly. :/
