How On-Device AI Stem Separation Works
PluckStem executes Meta's state-of-the-art Demucs v4 (HTDemucs) deep learning model directly inside your browser. By pairing WebAssembly SIMD with the ONNX Runtime Web engine, neural tensor math runs locally on your machine with zero server roundtrips.
🔒 Complete Privacy
Audio files never touch a remote server or cloud database. Processing runs entirely in browser memory.
âš¡ Zero Bandwidth Limits
No upload queues or file size caps. Separate as many tracks as your local hardware can process.
🎹 Production Ready
Export individual stems as uncompressed WAV files or package them directly into your DAW workflow.
Frequently Asked Questions
Does PluckStem require an internet connection after loading?
Once the ONNX neural model weights are cached in your browser storage on first use, stem separation executes entirely offline on your device.
What is the difference between MP3 and WAV for stem separation?
Lossless WAV files preserve full frequency resolution above 16 kHz, allowing the Demucs model to isolate transients in drums and vocal harmonics with fewer phase artifacts.
Can I use isolated stems commercially?
If you own or hold the copyright or commercial rights to the underlying music, you are free to use stems exported from Plectrum in commercial mixes, beats, or games.
