A Windows desktop app for musicians and producers. Paste any YouTube link, stream the audio live, and use AI-powered source separation (Demucs) to isolate and control individual instrument stems in real time — no file size limits, no subscriptions.
Paste any YouTube URL — no download needed. The app streams the audio directly and feeds it to the separation pipeline in real time.
Powered by Meta's Demucs model. Separates any audio into 4 stems: drums, bass, vocals, and other instruments — with high accuracy on real music.
Each stem gets its own fader. Want to reduce the drums and boost the bass? Mute the vocals entirely? Done — in real time while playback continues.
Play the separated mix in real time through your audio output. Designed for musicians who want to practice alongside or analyze songs.
Clean, minimal desktop UI. No complex settings — just paste a link, hit play, and control your stems. Built natively for Windows.
No upload size caps, no track limits. Works with any YouTube content — full albums, live recordings, anything that's publicly available.
🔬 About Demucs: Demucs is a state-of-the-art open-source source separation model developed by Meta Research. It uses deep learning to separate music into its individual instrument stems. It runs locally on your machine — no data leaves your computer.
This tool is in active development. If you're a musician, producer, or just someone who wants to practice with isolated stems — reach out and tell me your use case.
