This is powered by Spleeter, an open source project from deezer, but repackaged with a UI: https://github.com/deezer/spleeter

I haven’t downloaded the app to see if they do this, but it would be a nice to see an in-app about page tip their hat to spleeter. Not strictly required for MIT license afaik, but nice to see.

EDIT: They give credit in the settings page and link to github - perfect.

I agree. I make it a point to give credit where credit is due when building products, and appreciate when others do, as well.

That pretty much summarizes what's good and bad about the MIT license.

A demo would be nice on the website ... Sort like a before and after kinda of thing

I went ahead and uploaded a demo here: https://www.meanelephant.com/spleeter/

Don't judge my song choice, I didn't want any DMCA requests.

Well this is kind of amazing. For what it's worth, it does work, but it doesn't accept m4a files like the UI claims. I had to transcode them to flac first to get them to work.

(Also it would be nice if the players kept the same playback position when you switched between them.)

Very cool. Related, I've definitely spent a lot of time listening to and playing with the band Lawrence's stem player (https://stems.lawrencetheband.com/), which comes from their own recordings. Lots of detail that you might miss when it all comes together.

On mobile it doesn't tell you what platforms it runs on and clicking download immediately starts fetching a .exe

So I guess it's Windows only?

On chrome iPhone it downloaded a dmg for me, so it seems to do its best to autodetect. Kinda cool for their minimalist vibe, but can cause confusion if it messes up. If the project owner sees this, it’d be nice if “try it” revealed the platform downloads and on mobile didn’t attempt to download anything.

https://splitter.ai/ does the same thing without any downloads or charges

Messing around I tried this with the rap album MBDTF and didn't get much luck (lots of stuff tossed in the "Other" category, vocals sound terrible.) Then I tried it on the indie album Bambi and got much better results. Seems much better trained on certain types of music.

The biggest miss here I think is piano, seems very very specific.

There’s websites using the underlying technology (Spleeter) that are free to use like ezstems.com or splitter.ai.

Spotify URL's might be useful to add as a feature for input options...

Doesn't the open source Audacity do this as well?

Not as far as I know, no.

It kind of sort of does. You can go to effects > "isolate vocals" for example and it usually does a decent enough job.

There are lots of open-source tools that can do this, some requiring more effort than others.

This effect operates on the very simple logic that vocals tend to be the only fully centre panned channel in the mix. The same approach won't work for anything else, and won't work on older stereo recordings where hard left/right panning of vocals was a lot more common than nowadays

Not perfect, but for $15.00 it's great.

$15 is a tad bit much for repackaged open-source imho.
