Split

Six stems.

Splits run locally on your GPU with live progress, and presets isolate an instrument while the playhead keeps moving.

  • Vocals, drums, bass, other
  • Guitar and piano when you want them

Export

  • Any stem, or all of them at once
  • Any DAW that reads WAV files, which is all of them

This works so amazingly well, thanks a lot! <3

r/linuxaudio

excellent stuff.good quality for compressed audio.

r/linuxaudio

Awesome, I was waiting for something like this on Linux.

r/linuxaudio

That's awesome, thanks!

r/linuxaudio

Been enjoying it for a week or two

r/linuxaudio

I'll definitely keep this in mind for audio separation. I've used Moises for a long time until they went all AI.

r/linuxaudio

Daaaaamn, work really well

r/linuxaudio

For me, with zero knowledge of mixing and music production, your software is fantastic, it's so fun to play with it. Good job!

r/linuxaudio

Audio quality is really really good.

r/linuxaudio

Local processing is a nice distinction from the cloud tools.

r/macapps

I compared this tool with the stem separation in my FL Studio and this tool worked better. It took out the tinny noises, any hissing sound etc. without me having to run EQ in FL Studio. There is very little distortion. Much cleaner and so simple to use.

r/FL_Studio

Wow this would have come in so handy while I was still in highschool trying to find acapella only music for talent shows

r/macapps

I gave it a try on a Thrown song, and it actually worked really well, man. Well done on this.

r/macapps

Wow! The app looks super useful and it's free and opensource. That's awesome!

r/macapps

Really like the local/no-account approach. The synced video + stems makes it feel more like a practice tool than just another splitter.

r/macapps

been looking for something like this. I use like 2 different websites to download the MP3 and then split. this'll speed things up much more smoothly. thanks!

r/FL_Studio

very good separation and on par with other services that use the same model!

r/FL_Studio

Love the program, been using it for the past days and it has been really helpful! <3

r/FL_Studio

I'm very impressed with how well this works.

r/coolgithubprojects

r/coolgithubprojects

Holy shit and it doesn't look like AI slop!!! Nice one.

r/SideProject

Beautiful idea. Gratz on accelerating music development.

r/SideProject

The local-first call is the whole product. Subscription splitters always felt like renting a button.

r/SideProject

this is amazing, thank you

r/SideProject

Works beautiful on my mac m3 max.

r/SideProject

r/SideProject

r/SideProject

r/SideProject

Very, very cool. Well done!

r/SideProject

Nicely laid out and excuted. Well done!

r/SideProject

This is absolutely amazing. Havn't tried the paid software but it's just baffling to me that you can se a post, someone makes free software, and it just works on my linux mashine together with my nvidia card. Feels very polished, good UI and just installs everything for you. Great job my guy

r/SideProject

black magic. i would have killed for something like this when i was a kid an started lerning guitar and drums
