It's in the first paragraph of the README in the github repo and th3 second paragraph on the website. I'm not sure what more can be asked of the author.

Thanks - I didn't even notice there was content below the fold on the web site (I'm on a desktop browser). How about saying so above the fold?

Original Demucs author here. Thanks for putting forward our research! I’m definitely happy to see more front ends for Demucs being developed and to read that it has been useful to other musicians! We are working on the next iteration of the model, and with more sources, hopefully released by the end of the year :) If you are interested in this research you can follow my Twitter (@honualx) or star the Demucs repo.

I'm curious, what is the business justification for funding development of Demucs, if you don't mind me asking? It doesn't seem very related to FB's core business.

Solving problems like audio source separation (eg. Distinguishing multiple speakers in a noisy environment, or picking speech out of a background where music is playing) seems very much in FB's wheelhouse.

It's even easier than that. There's a few npm libs around that are dedicated to shipping a copy of ffmpeg with electron.

even easier than what i already have on my system? what are you saying here, as it makes no sense to me

How about you stop being so pedantic and admit it when you're wrong instead of digging a deeper, dumber hole.

This is a real design problem - many web sites do this.

Saying so and suggesting an alternative isn't being pedantic.

Honestly, this sort of thing is cool; but why (in general) is it necessary in the first place? If the elements of the song are recording in isolation - which they are in all studio versions, why can't we just move to a format that supports the layering?

Musicians and studios don't generally tend to offer the public access to original stems for songs (why would they?) Say that you want to make a remix, mashup, or otherwise use sound-bytes from a song. The easiest thing to do is use a tool like Spleeter/Demucs to separate the source layers so that you can then further process them in your DAW. This is what I do, but I just use the Demucs CLI because it's simple enough…

Are there no communities of "open source" music? It sounds like the stems are part of the "source code" for tracks.

"Download and extract the latest ffmpeg snapshot from evermeet.cx and place the ffmpeg executable inside" Why? Why can't this just point to the location where ffmpeg is rather than making a copy of ffmpeg? symlink might work, but just do a $(which ffmpeg) or ask the user for the path ~/bin/ffmpeg /usr/local/bin/ffmpeg etc

ffmpeg has not had a stable command line interface for some time. It can be a problem to assume that the system-installed version accepts the arguments you plan to give it.

Tried splitting a complex arrangement (Chicago by Sufjan Stevens). Drums bass and vocals come out fairly well, though the drums stem seems to lack other percussion elements outside of the core rock drumkit (e.g. tamborine), and cymbals hits are clipped rather than ringing. The 'other' stem, the rest of the instrumentation, keeps a fair bit of the percussion and there's bleed from the vocal melody. The backing vocals…

Did you use a FLAC/WAV file? That should yield the best results. (Only asking because you linked to YouTube, and I'm not sure if you used the YouTube audio for your source.)

I can't find any way to do this.
