Yeah by now I was hoping that we’d be seeing more “upscaling” of audio processes like we do with images.
Of course this could probably add as many artefacts as remove but I’d be interested what it could do with a separated vocal stem, re-adding lost harmonics and sibilance etc.

Is this a new one ? 14 stem types sounds very different to the recent posts I read here.
Comparing splits I’ve done in Koala vs Logic Pro for iPad, generally the logic ones come out a bit cleaner. While I suspect it’s the same tech under the hood, I think Apple have tuned the algorithm a bit.

Koala is using Spleeter while the latest splitter algo is demuc 4 ht. Have feature requested for an upgrade.

Managed to install StemRoller. Big difference in-between it and Demucs-GUI is that StemRoller is 2,2GB large app while Demucs GUI is only 500Mb. Demucs runs locally with MPS (Mac GPU support), not sure about StemRoller. In Demucs you can choose the specific stem you want to extract and not spend time on all. Demucs GUI doesn’t claim to be AI when in reality it is just an algorithm and it doesn’t run some shady connections.
Logic is dope… new update made alot of my third party programs obsolete… Im also not that much of a stickler for “the best…” some artifacting lends itself to texture

Demucs uses a ML library, so that’s not an inaccurate claim. The training model is local, it’s “AI” similar to Topaz video cleanup etc. “ML” and “AI” were used pretty confusingly interchangeably until generative slop companies started polluting the public understanding of what ML is.
Hrm, the latest Demucs GUI was 5GB for me fully un-7z’d on a Windows box with CUDA.
I’ll probably stick with that instead of Stemroller still, thanks!
I know the app had a lot of bells and whistles to let people download from Youtube but like, I don’t need any extra features baked in so fine with getting rid of the bloat.

Apologies if this has been mentioned already. I’m using Splitter from Bandlab.com. Works for me. Never invested any time comparing it to other solutions. Stems are getting highly mangled anyways, hence no need for perfect quality.
As a Serato user, I was thinking the other day of buying Serato sample to use in Ableton Live. But after watching a workflow video, it made me realise that I could just use my Serato DJ software to grab out the stem split files.
I’m going to give it a try tomorrow as I’ve always been pretty happy with the stem splits from Serato.

You can here the difference in-between Spleeter and Demucs 4 ht here. Better extraction of, in this case, vocals and retaining the full range without beat leakage:
Original
Spleeter (Koala app)
Demucs 4 ht

This sounds great. I’ve just bought a Mac mini m4 and would love to use it to split tracks. Is there an “easy” demucs 4 (ht?) installer with gui you can link me to? I’m a Mac noob and keen not to go into any compile type of business…thanks!

I want to extract a lead I played on my Prophet a few years ago from a recording that also has drums and a bass in it. What’s my best shot at this with free tools I can use on my Mac / in Ableton in 2025?

The latest ableton beta has stem separation built in
It works well , fairly quick and quality seemed good
The beta is free

Ah nice, thanks! I’m still on Live 11, I guess I could install the trial of 12 for that? Or will that not allow me to use the beta version?
I don’t know , check the website for t&c’s
You may need a current license for 12 …
Otherwise there’s a lot of free tools mentioned further up this thread

If you want it crunchy you could use Koala. If you want a little better quality you could rent Logic iOS for $5 then cancel it and rip a bunch of stuff for 30 days. I wonder if MPC beats got that stem sep? I guess MPC2.x or whatever does it.
Demo Serato Sampler and use it for the one off intended purpose. That’s all I got at the moment.

My super-techy son has asked me why anyone would pay for any of this stuff when Ultimate Vocal Remover is brilliant, open source and free. https://ultimatevocalremover.com

Plus I don’t like new products being plugged and then praised by new users, makes me immediately suspicious
