Since this isn't exactly new, I will share this: ezstems.com is a web-implemented Spleeter, seems free to use
For anyone who's curious, I grokked this about 6 mos ago. It works spookily well on standard tracks. As you might imagine, when you have instrument timbres that are similar to the human voice frequency wise the results aren't as clean. But it's a really nice tool to have in the toolkit.
Oh my... this is just great. Definitely worth to try at least the online free version (limited to 30 sec)
Absolutely insane what has become possible in recent years with neural networks. Tried ezstems.com with a few standard commercial songs, and the separation is essentially perfect. What the heck. A human couldn't separate them better in their mind!
@SevenSystems Agreed! In a similar vein, though it isn't neural, there is an open-source mastering tool. Give it your reference, give it your mix, and it only takes a few minutes. It's called Matchering. It can be installed and run with Docker. And then it runs in your browser as a local server.

@animalelder the downside of it is probably -- will there be ANY jobs left whatsoever by 2050 that still require humans? 🧐
But seriously. "Normal people" can't even begin to appreciate the incredible research and science that is behind stuff like these stem separators. (no offense to normal people!). All of this stuff would've been considered utterly impossible 10 years ago.
https://melody.ml/. Is another web based splitter. 2 or 4 tracks - only spits out MP3 but seems to do a good job. Warning - You need to give up your email.
Cool thread

Clever
Has anyone tried running Spleeter on an iPad with one of the available python interpreters?
I didn’t realize there was another thread on this.
Trying to figure out install now. Seems like nothing happens when I test, so I’m surely doing something wrong.
Thanks so much for trying. If you get it working, I'd love to know. Getting command-line commands installed and running definitely a hole in my skill set.
Sadly, I forgot most of what I discovered early on about how to manually get through uncooperative installations. I’m lousy at taking notes.
I only got it working on my mac cuz there was a step-by-step walkthrough that involved installing anaconda which seems to have done a lot of the heavy lifting -- but it was all voodoo to me.
Unfortunately Spleeter is only supported on Python 3.6 and 3.7. Pyto (my iOS Python environment) is 3.8.
I’m trying using iVim, which seems to be able to run Python 3.7, but so far getting errors I haven’t been able to work out trying to install.
FWIW, my notes from getting it up and running on pc
I found this video helpful

You first have to install spleeter from within python
https://github.com/deezer/spleeter/wiki/1.-Installation
Run spleeter from python command prompt
There's a "spleeter" subdirectory inside of the "spleeter" root directory. For some reason, I had the best luck running spleeter from the spleeter subdirectory inside the root
Separate track into two files - vox + everything else
spleeter separate -i audio_example.mp3 -p spleeter:2stems -o output
Separate track into 4 stems - vox+drums+bass+other
spleeter separate -i audio_example.mp3 -o audio_output -p spleeter:4stems
Audio files are stored here (using “audio_example.mp3”):
C:\pathtodirectorycontainingspleeter\spleeter\output\audio_example\
