Split any song
into stems.
Drop in a track and pull it apart into vocals, bass, drums, and everything else. It runs entirely on your own device — no upload, no cloud, works with the internet off.
Interactive demo
Watch it separate.
100% on-device. Your audio never leaves this machine.
How it works
Three steps. No account.
Pick a track
Choose any song from your device — MP3, WAV, FLAC, or M4A. Nothing gets uploaded.
Run the model
HT-Demucs runs on your GPU (Metal on Apple) and splits the mix into four clean stems.
Keep the parts
Play each stem, mute what you want, and export the ones you need. All of it stays local.
On-device by design
Your audio never leaves this machine.
The separation runs locally with HT-Demucs on your own GPU. No servers, no accounts, no copies of your music sitting in someone else's cloud.
Take it
everywhere.
One separator, every device. Download the SplitFire app and start pulling songs apart in seconds.
