I tried throwing some underground rap artists at this app, as stem splitters usually struggle with them

I split https://www.youtube.com/watch?v=DDaL7KBjkDI

And it gave me this https://www.dropbox.com/sh/inyk38n2jrp5i45/AACpB0xXNFxamEmP3... I noticed some weird hissing with the 808s, but other then that it sounded pretty good

For more of a challenge, I inputted https://www.youtube.com/watch?v=uAwQ3njiU4M

and it came up with https://www.dropbox.com/sh/97lzke0puh9dzeo/AACE75vsbNS43UqqH... It was able to separate some of the kicks from the 808s, which is really impressive to me!

Overall, I'm very impressed! This sounds much better then lalal.ai to me

Been using demucs for a couple of weeks now, mostly taking my early produced music which I have since lost the project files for and giving them a remix and update. Gotta say I have been blown away by how good demucs is. I installed it following the repo instructions and then created a zsh alias to run it with any file name. Eg $ai_split mySong.mp3 Wait fifteen minutes and out pops four stems, flawless so far, even b…

This testimonial almost has me wanting to try it on an “album”[1] I recorded when I was in a “band”[2] in high school. I too lost all of the source files[3].

1: On second thought maybe not. It has not aged well.

2: Me and another kid, with a guitar, a pre-OS X Mac, a pirated copy of Rebirth, a pirated copy of SoundEdit 16, and literally the mic that Apple used to include with (some?) Macs. I’d back-reference[1], but our equipment was not the problem. Well, except for [3].

3: I learned my lesson: I should have been older and had a job that would afford me a backup drive, so I could sample the sounds of that dying HDD and retcon the samples into my “album”[1].

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 seem to have disappeared for the most part, and are only audible in the vocals stem when the lead vocal is present (like they're reverse-ducked? Been a while since I did any production, the terms have escaped me...).

Not much use with complex arrangements to be honest, I was hoping to get things like the strings section separated from the rest of the arrangement.

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 does seem rather disingenuous that the product page makes no mention that the author didn't do the heavy lifting, and that at the same time it features a prominent donation button.

If I didn't know who did the real work and benefitted a lot from this tool, I'd give to StemRoller in proportion to my gratitude -- which I'm sure others are liable to do.

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.

Why do vocals.wav, other.wav, and instrumental.wav all start out the exact same (with vocal sounds)?

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.

I dabble in audio production in my free time outside of work, and I typically will use iZotope RX 9 or Neural Mix Pro for isolating vocals or stems. However, these are paid products, and it's encouraging to see more open source projects being built around this space.

I like the opportunity to view the source code and learn from it, as opposed to most paid products which are typically closed-source and a bit of a "black box".

Sure - this is mostly just an accessible frontend for Demucs, but that's still okay. The author clearly indicates that in his repo, giving credit where credit is due. Additionally, this helps less-technical creators be creative in new ways.

Thanks to all who contributed.

"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

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
