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 r…

Thanks for the kind words!

Labeling the 4 parts Vocal | Melody | Bass | Drums, instead of Drums | Vocals | Bass | Other would go a long way to making it seem less programmer-y.

Nice idea! The name 'other' comes from the traditional datasets used to train these models, but I'm open to trying to incorporate a better name.

While this might seem to be intended for DJ remixes a demixer also lets you jam along to your favorite songs. For instance you can extract only the voice, bass, and drums and play along with your guitar like you were a part of the band.

Not to mention arranging or just notating songs.

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.

freemusicdemixer would endlessly try to download files and never actually load for multiple minutes, though it might be my Wi-Fi. demucs seems to work acceptably on music, but transients tend to get lost unless you unmute the drums channel (which is probably unavoidable whenever drum and tonal transients coincide in time and occupy similar frequencies).

Oh my god, stemroller.app is 1.85 GB (weights only 350 mb) electron python pytorch ffmpeg and 10 MB webapp. This is state of modern app development. But it works, nonetheless.

It didn't load weights for me, So I tried umx.cpp but it failed to compile on mac. I would recommend to polish umx.cpp and put converted weights on huggingface, make it as effortless to use as whisper.cpp etc.

Can you create a github issue? Dod anything show in the developer console?

I could (probably) improve umx.cpp but freemusicdemixer.com is supposed to be the "effortless" compile-free version of it.

Sorry about that - could you put the contents of the developer console or the symptoms in a github issue (or describe it here?)

I frequently use a similar online demixer and am always worried that they will eventually remove the free option, so was excited to try this one out. When uploading couple different 2 minute song mp3s it didn't work and would always produce 5 identical wavs that just contain some audio pop/click sounds. It worked when i cut out a 30s section of the song. So some indicator if the process failed or not or what are the length limits would be appreciated. Still nice work, will be keeping an eye out for any updates to this, keep going!
