I've always wanted a way to extract just the kick drums in realtime but I don't understand this field well enough to understand whether it would be remotely possible or not.

You want just the beat, ie the time markers of each kick? Or you want the isolated sound (ie audio) of each kick? Both are generally possible today, though the approach will differ a little bit.

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.

Many niches in electronic music have small knit communities of creators and producers that regularly remixes each-others stuff. But it is not an open community, you gotta have a decent standing (from making own music or prior remixes) before someone is willing to send you their stems. For anyone musician that has a label/publisher, they also need to be in the loop, for handling of the royalties. So sharing stems happen regularly in the music industry, but it is not easily accessible. Which makes tools like the one mentioned very useful for everyone else that would like to participate.

Not to be dismissive, but as far as I can tell, the heavy work is done by facebook's demucs and this is an electron front end to run the demucs cli (and I guess search youtube for videos to download). The demucs project page has more information. https://github.com/facebookresearch/demucs

There’s no need to be dismissive since they say this in the first sentence. Preparing an easy to use app for all platforms probably does get this into more creative hands, and that’s a net-positive contribution I can appreciate.

It should be in the title.

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?

This is like asking why we need decompilers.

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.

> It does seem rather disingenuous that the product page makes no mention that the author didn't do the heavy lifting,

It does seem rather disingenuous that your replies make no mention of admission for making a factually incorrect statement in the first reply.

Not a big deal to me personally, but it is not surprising that some people see this as being petty.

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.

Just a guess here, but I wouldn't be surprised if it's used to better spy on your messenger audio conversations. They already listen in and will pick up keywords to populate your FB ad stream.

A couple of commenters have mentioned using lossless files, but so far no one has said HOW.

Maybe use demucs directly? https://github.com/facebookresearch/demucs

Thanks. The comments seemed specific to this front-end, but maybe.

How do you load a local file?

There is no support for a such thing, this is software in year 2022, never local, online first.

Hahah, I know, right? People actually believe that shit... until they get jacked by a service provider.

Open Culture recently posted a link to Abbey Road but with only Paul's bass lines, but the actual content got taken down. [0] It was really cool though, in part because it's not nearly as precise as I would have thought, which made it feel really organic.

In the real world where tracks are cut live, there is a fair bit of microphone bleed

I imagine studio-era Beatles in particular would be difficult.

Microphone bleed, lots of overdubs (especially vocals), and repeated re-layering tracks on tape over and over due to channel limitations. They really were doing crazy stuff with limited tech.

I think this would be hard for bands that really fill the spectrum and don’t have that clean treble, mid, bass separation. Or recordings really compressed into a frequency range.

Now this makes me want to see what happens with like My Bloody Valentine and Husker Du :).
