I built a free Open Sourced, local audio stem separation
StemDeck is a free, open-source tool for local audio stem separation that allows users to process their own audio files without uploading them to the cloud. It supports various audio formats and provides features like a DAW-style mixer and stem extraction. While it is a functional alternative to commercial products, it may lack some advanced features found in paid services.
- ▪StemDeck allows users to separate audio into up to six stems, including vocals and instruments.
- ▪The tool runs entirely on the user's machine, ensuring privacy and control over audio files.
- ▪It is designed for personal use and does not require an account or subscription.

Opening excerpt (first ~120 words) tap to expand
Free, local stem separation. No account. No upload. No subscription. JOIN THE COMMUNITY Drop an MP3 or WAV, or paste a YouTube URL. StemDeck splits the audio into up to six stems (vocals, drums, bass, guitar, piano, other) and plays them back in a DAW-style multitrack mixer. Mute, solo, mix, zoom the waveform, loop a region, and download individual stems or a custom mix. Everything runs on your own machine. What is this? StemDeck is a stem separation tool, not a downloader. Its primary use case is processing audio files you already own — drag an MP3 or WAV onto the import bar and go. YouTube URL support is provided as a convenience for content you have the right to process. StemDeck does not store, cache, or redistribute any downloaded content.
