Quick intro if you're new here: StemDeck is a free, local audio stem separator. You drop in an MP3 or WAV, it splits the track into vocals, drums, bass, guitar, piano, and other stems right on your machine. No account, no upload, no subscription, no usage limits. Open source, runs on Windows and macOS.

This one has been a while in the making. v0.5.0 is a full UI overhaul. The goal was simple: stop looking like a web app and start looking like something you'd actually open next to your DAW.

What changed in the interface

The mixer and waveform lanes now sit side by side in a proper two-column layout. Rows fill the full height dynamically, so there's no black gap when a track has fewer stems. Non-extracted stems are grayed out in both the mixer and the waveform, which makes the separation result immediately readable.

The transport info moved to the footer: album art, title, time position, stem count, all always visible while a track is running. Below that is a full-width scrub bar. When nothing is loaded, the footer shows a decorative waveform placeholder instead of an empty shell.

Export Mix works now

This was broken in a subtle way. If you had all 6 stems selected, no mix file was produced at all and the export silently failed. That's fixed. You can now export your current stem mix as WAV or MP3 directly from the footer. File names are clean underscores, no spaces, no special characters.

A few smaller things worth knowing

The footer waveform used to pull from the first available stem, which on an instrumental section meant a flat line. It now uses the full reconstructed mix, so what you see matches what you hear.

Tag search with autocomplete: type # in the library search box and a dropdown shows up to 8 matching suggestions. The library sidebar got new sections too: Recent, Stem Collections, Tags, and Favorites, with subfolder nesting via drag-and-drop.

The analysis panel now includes a Dynamic Range score with a label (Compressed / Moderate / High / Wide), Tempo Stability as a percentage, and a Key Confidence meter.

The website

I'm a father building this in the time I can find between everything else. To get a website up without it taking three weekends, I used AI to help put it together. It's live at stemdeck.app. Not perfect, but it's real and it's there, and it means the project has a proper home.

If something breaks in 0.5.0, please open an issue. Every report goes directly into the next cycle.

Hey everyone,

I’ve been working on an open-source project called StemDeck where today I believe I finally reached a nice milestone for the project:

StemDeck now supports native Windows and macOS clients were main goal was reducing setup friction and making the app easier to run outside Linux/dev-focused environments.

While im still actively improving the project any feedback is very welcome especially around:

• UX/UI
• performance
• workflow
• stability on different systems

GitHub and latest release that I'm realy proud of :)

Also I'm not sure what other comunities or resources I could share this tool ,so any guidance on that would be more than welcome too

Edit:

Corrent link for the latest alpha release: Release v0.4.0-alpha.1 · stemdeckapp/stemdeck

I’ve been building StemDeck, a free and open-source alternative to tools like Moises for separating YouTube tracks into stems.

You paste a YouTube URL, choose which stems to extract, and the app generates isolated tracks like vocals, drums, bass, guitar, piano, and others. The interface is designed more like a lightweight DAW, with waveform views, mixer controls, stem-level VU meters, mute/solo-style toggles, and per-stem downloads.

It’s still early alpha, but the core workflow is working and I’d love feedback from people interested in music tools, remixing, practice, audio analysis, or open-source AI apps.

Repo: https://github.com/thcp/stemdeck

Main stack includes Python/FastAPI, Demucs, yt-dlp, FFmpeg, and a custom browser UI.

Feedback, bug reports, and ideas are welcome.

Took a while to complete but this beauty is my first bass that I ever made :)

Components:

• Wood
  • Wenge
  • African Mahogany
• Pickups
  • Bartolini BD 5 C BC B
  • Bartolini BD 5 C BC T
• Preamp
  • Bartolini NTMB+F 3-Band Bass Preamp
• Knobs
  • Schaller - Strat knob 6,0 mm
• Locks
  • Schaller - M4 90
• Bridge
  • Schaller - 3D-5

I'm so proud of the sound of this guy, I honestly can't believe that I was able to build something like this.
