Stem Separation - Best Results

  • So…can anyone confirm Logic Pro Version 2.2 For iPad can separate stems down to the kit level and can it separate lead and backing vocals? The version description is ambiguous

    Can I make a suggestion? I’ve always loved this old record. For those with the tools, and willing to participate, could you do a full stem separation (including Drums) and share the results for the community to compare results? Who knows, perhaps we could eventually even have a remix competition and try test material from other forum members to compare results?

    Are you "Billy Paul" or are you the copyright holder of that material? Because without permission from the rights holder this could get one into a lot of legal troubles.

    I sure hope Billy Paul isn’t posting here because he passed away.

    Even in the event of a person's passing, the rights for published music typically go to their next of kin, their estate or an IP holding company.

    No, it does not

    Oh thank you. Moises doesn’t either with Premium they reserve that for the much more expensive Pro subscription

    Blimey, I hadn’t noticed that pricing tier in Moises. That is expensive!

    But bringing back Billy Paul = PRICELESS! 😉

  • I think I’d use the free or cheaper options to go on a voyage of discovery and adventure, making mock ups, and would only consider the more expensive options IF a forum-member-worrying track popped out 😉

    There are a lot of artefacts and bleed from the free/cheaper options. Moises gives the cleanest stems so far but StemRoller gives you the drums

    I'd avoid Fadr. I opted in for a sub for the pro version and tried a couple, and anything other than a trio (instrumentally speaking) is simply awful...muddy and indistinct results.
    Tracks with vocal are a TINY bit better, but the results would best be described as "for rehearsal purposes only"

    It should be stated that more than likely all of these solutions use Demucs of Spleeter essentially. Perhaps forks of them but at the base it’s probably using those two. I could be missing another leading model so add that to these two but it’s because of open source software that a majority of these companies have their own systems in place.

    YMMV if you feel one is better than the other, but I doubt there’s any one if these that will be miles ahead of another in the pack.

    Remember that editing files afterwards that are close to your intended target is another great way to fix any missed issues. Whether that’s removing some background noise, cleaning up some leaked audio here and there, filtering specific frequencies, that’s essentially what these programs are doing.

    These algorithms are all trained to look for specific frequencies and can, often, sus out the noises specified and then get rid of the rest and leave it as ‘drums’ or ‘vocals’ or what have you.

    Maybe they’ll be a leap forward one day, but considering how long many of the underlying research has been around and the little progress forward since, I imagine it’ll be small incremental changes utilizing technologies that do clean up process for us, that may or may not be ai related but will certainly be marketed as such, or ai washed if you like.

    Some papers of note

    I would be curious to know what the new stem separator in Logic Pro for Ipad and LP4 Desktop uses. It is IMO a lot better than even the Transcribe+ that I have been using regularly as my Go-To for the past few years. Not only is it a lot cleaner but now it adds 2 additional stem tracks (Guitar and Piano)!

  • I read that Moises is built on top of Spleeter, the open-source library developed by Deezer. However, Moises likely enhances Spleeter with their own proprietary code and models, as shown by its ability to separate more than four stems (up to seven) which is more advanced compared to standard Spleeter implementations, which typically handle two to five stems.

    As mention above, from all the examples people kindly DM’d me, Moises was by far the cleanest - though I still don’t have an example of the Moises Pro version drums yet, if anyone has a Pro subscription and is willing to participate privately. Whilst some of the other platforms do drums, there are a lot of artefacts. As rightly mentioned above, these can be dealt with, to a degree, but I’d love to hear a clean copy. Logic doesn’t do drums (yet).

    The Logic stem separator does drums. It does them quite well in fact.

    Ahh we were told further up the thread that Logic didn’t separate to a kit level? Would love to do a private comparison if you’re willing to do an extract from the track posted on page 1. Just DM me direct, Mum’s the word. No need to confirm or deny here 🤫😉

    If you have an iPad that's compatible with the Logic stem splitter, Logic is free to try for a month, and could be used for $5 in any later month you might need to use it. If you offload the app when not needing it, then it won't even hog storage space on your device.

    That YouTube video is on the official Billy Paul channel, so just playing the video provides income for Billy Paul’s right holders.
    Hopefully, it’s family but it might be the record company. There’s a store literally on the Bill Paul page to buy albums. So,
    chances are this use of the track would pay dividends for the Billy Paul trust. Like as much as $0.83 considering who will actually
    participate to ID the ideal stem splitter. I think we all want the results but it takes a few dedicated souls to make it happen.

    Clicking on the YouTube video is all fine and good and it sends a little money to the rights holder. The original poster asked someone else to commit copyright infringement on their behalf and post "stem" files here for them. Does that seem like a good idea? Doesn't to me.

    As far as I can tell it will separate out a drum track for you but not individual tracks for kick, snare, hats etc. I assumed that was what you were asking. I’m happy to stand corrected on this though, if there’s a way to do this in Logic I’m all ears. It would be really handy.

    The spirit of adventure and discovery lives on 🤣

    I love irony, interestingly, and completely unrelated, "Neum" (or "neume") is a musical term used to indicate pitch and rhythm for Gregorian chants. It comes from the Greek word "pneuma," meaning "spirit".

    Either is good enough, it’s the cleanliness of the samples I’m looking to assess, the lack of bleed and artefacts 👍

    You are correct. It does not separate the drums. I responded to the comment that Logic doesn't do drums. It does do drums but not to the kit level.

    No problem. The thought of drum stems and background vocal separation for creating Karaoke tracks has me intrigued. I may try it for a month or two....

    Wow! Apple, aka Big Brother must be monitoring this thread and getting ideas from us. They're probably gonna buy Moises for $10 million and include it in the next Logic Pro update!
