StemRoller – Isolate vocals, drums, bass, and other stems from any song
- raydiatian 4y agoHow does it perform compared to Deezer Spleeter or lalal.ai Else who cares
- phoe-krk 4y agoAre there any public examples of the split audio files?
- setgree 4y agoOpen 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.

- TylerE 4y agoIn the real world where tracks are cut live, there is a fair bit of microphone bleed
- hammock 4y agoEspecially in the day and style that the Beatles recorded. Today, not so much
- salmo 4y agoI 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 :).

- elaus 4y agoThis seems to run just fine under Linux as well, not completely out of the box though: It's basically missing builds and config for Linux which can be build analogous to the existing Win/Mac stuff. You also have to build the demucs-cxfreeze dependency (as described in its repo, https://github.com/stemrollerapp/demucs-cxfreeze https://github.com/stemrollerapp/demucs-cxfreeze).
- elaus 4y agoIt's almost eerie how well this works with electronic music. Coming from an age where your best try to separate a track was using equalizers, I didn't have high hopes. Trying it out with Alan Walker's Alone, it separates the vocals and drums almost perfectly. Bass is really fine as well, only instrumental and 'other' was a bit mixed up in my try.
- knicholes 4y agoWhenever I see an "##Installation" section with more than one step, I immediately call DOCKER!
- nr2x 4y agoHow is this similar/different than the Deezer one?
- CharlesW 4y agoI'd also be interested in how it compares to iZotope RX's Music Rebalance (examples from earlier releases here: https://www.izotope.com/en/learn/stem-isolation-music-rebalance.html https://www.izotope.com/en/learn/stem-isolation-music-rebala...).
- avis 4y agoI'd be interested to know how it compares to iZotope as well as phonicmind.
- pcf 4y agoI just checked "Californication" (used for all their other examples here: https://soundcloud.com/honualx/sets/source-separation-in-the-waveform-domain https://soundcloud.com/honualx/sets/source-separation-in-the...) in RX9 Music Rebalance with the setting to "best", and I wasn't very impressed. Seems like this tool might be better than Izotope's.
- ksherlock 4y agoI just did a quick test of demucs vs spleeter:4stems. demucs is significantly slower but the output is better. in a semi blind comparison, I prefer demucs for all 4 tracks (drum, bass, vocals, and other). bass and other stand out the most so let me say a couple words about them. bass - the demucs bass has less bleed from other instruments and the volume is consistent throughout. with spleeter, the volume varies a lot and there are multiple sections of 1-2 bars where it just drops out completely. In Capo, the demucs spectrogram is nice and clear whereas spleeter tends to look like pencil smudges for the most part. other - with spleeter, whenever there are vocals, the other instruments turn to mush. demucs is much better. Oh, you can tell people are singing -- the instruments get muffled -- but you can still hear them.

- abbusfoflouotne 4y agoWould appreciate an easier way to download and run this! The steps on the readme are pretty long, at least for me (Mac user)
- interestica 4y agoHow does it compare to lalal.ai ?
- ksherlock 4y agoNot 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 https://github.com/facebookresearch/demucs
- pininja 4y agoThere’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.
- SebaSeba 4y agoThey did not prepare it for all platforms though. Linux is missing.
- pininja 4y agoLooks like someone’s on it. https://github.com/stemrollerapp/stemroller/pull/2 https://github.com/stemrollerapp/stemroller/pull/2
- TimTheTinker 4y agoIt 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.
- frob 4y agoIt'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.
- dylan604 4y ago"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
- Rodeoclash 4y agoIt's even easier than that. There's a few npm libs around that are dedicated to shipping a copy of ffmpeg with electron.
- dylan604 4y agoeven easier than what i already have on my system? what are you saying here, as it makes no sense to me
- deleted 4y ago[deleted]
- linux2647 4y agoMaybe there’s some feature of bleeding edge ffmpeg that’s required for the app
- PaulDavisThe1st 4y agoffmpeg 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.
- ccn0p 4y agotalk about a missed opportunity without examples. did I miss them somewhere?
- phonescreen_man 4y agoBeen 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 been messing around with mainstream tracks and using ableton with warp applied to quickly build out remixes. Demucs is going to be /is already a game changer!
- pininja 4y agoThat’s awesome! I wonder if there are projects to create a repository of pre-split public domain music? Seems like something the internet archive could host once created.
- eyelidlessness 4y agoThis 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].
- anderfernandes1 4y agoWow
- djcannabiz 4y agoI 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 https://www.youtube.com/watch?v=DDaL7KBjkDI And it gave me this https://www.dropbox.com/sh/inyk38n2jrp5i45/AACpB0xXNFxamEmP3vr3AImEa?dl=0 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 https://www.youtube.com/watch?v=uAwQ3njiU4M and it came up with https://www.dropbox.com/sh/97lzke0puh9dzeo/AACE75vsbNS43UqqHQeGMpMua?dl=0 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
- metadat 4y agoWhy do vocals.wav, other.wav, and instrumental.wav all start out the exact same (with vocal sounds)?
- pelagic_sky 4y agoI’ve found Lala to be my go to. If this is better, then I’m very interested in trying it out.
- pelagic_sky 4y agoJust a follow up. My two conversions so far, Lalal.ai has been better. Especially separating drums from instruments. I'll give Stemroller a few more tries as I am always looking for options.
- djcannabiz 4y agowhat genre of music, may i ask?
- pelagic_sky 4y agoRNB, NeoSoul, Trap
- screech 4y agoJust wow! There were methods extracting acapellas from tracks, but this tool here is another level. Fascinating how good the results are.
- thisiswater 4y agoTried 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. Original: https://www.youtube.com/watch?v=tWX3El-slpY https://www.youtube.com/watch?v=tWX3El-slpY Output: https://file.io/etpOQt57ziKe https://file.io/etpOQt57ziKe
- pcf 4y agoDid 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.)
- thisiswater 4y agoPerhaps you're right, I'd have to check. I typed the song in the search and pressed the first likely result, which is the youtube video I linked. Using the software as intended I believe.
- marssaxman 4y agoYouTube audio is optimized for bit rate, not quality (128K MP3). You will get better results with a higher-bitrate MP3 (320K would be good), better still with an uncompressed format like FLAC or WAV.
- NonNefarious 4y agoI can't find any way to do this.
- 4y ago
- eshack94 4y agoI 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.
- polishdude20 4y agoThis is awesome! Tried it out on Rush's Tom Sawyer and it splits out the vocals great! I can see this being super useful!
- Dwedit 4y agoLet's see how long it takes for some new Neil Cicierega remixes to appear now.
- intvocoder 4y agoWith a tool like this, you could get back into the animutation scene. (Edit: I guess it's a bit of a non-sequitur, but I enjoyed Suzukisan, so there's that.)
- yarg 4y agoHonestly, 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?
- gavinray 4y agoMusicians 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. https://github.com/facebookresearch/demucs https://github.com/facebookresearch/demucs
- pabs3 4y agoAre there no communities of "open source" music? It sounds like the stems are part of the "source code" for tracks.
- jononor 4y agoMany 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.
- osigurdson 4y agoIt isn't really in the best interest of the artist to provide this. The final mix is part of the overall product / work of art. Providing all of the individual tracks (there could be 30 or more in total) would also take up a lot of space / increase processing requirements while benefiting very few.
- volkse 4y agoIs there a VST front end?
- chriscjcj 4y agoIs there a way to process my own audio file rather than choosing one from YouTube?
- NonNefarious 4y agoA couple of commenters have mentioned using lossless files, but so far no one has said HOW.
- nextaccountic 4y agoMaybe use demucs directly? https://github.com/facebookresearch/demucs https://github.com/facebookresearch/demucs
- NonNefarious 4y agoThanks. The comments seemed specific to this front-end, but maybe.
- nerfhammer 4y agoI'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.
- jononor 4y agoYou 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.
- NonNefarious 4y agoHow do you load a local file?
- diimdeep 4y agoThere is no support for a such thing, this is software in year 2022, never local, online first.
- NonNefarious 4y agoHahah, I know, right? People actually believe that shit... until they get jacked by a service provider.
- atoav 4y agoFor all who look for something like this, iZotope RX (the audio retouche software) has a function called "Musical Rebalance" which is great for reducing spill or changing the balance in a live recording.
- colecut 4y agoAnyone else just getting 'failed' on every song they try?
