Why EZStemz
Everything runs on your machine.
100% local
Separation runs on your CPU — audio is never uploaded for processing. The desktop app works offline. Create a free account here only to buy your license and download installers.
6-stem model
Drums, bass, vocals, guitar, piano, and other
Mix and export
Mute, solo, and gain per stem. Export 44.1 kHz WAVs to your DAW or mix in the app using plugins.
The workflow
Drag, wait, mix.
You don't pick a model, you don't set parameters, you don't reach for the terminal. Drop a file, watch a progress bar, then drive a transport like any other DAW.
Drop in your audio
MP3, WAV, FLAC, AIFF, OGG, plus M4A on macOS.
EZStemz separates the stems
About 2–5 minutes for a 3-minute song on Apple Silicon. Longer on Intel.
Mix the stems live
Per-track gain, mute, solo, scrubable transport, master gain. WAVs sit in your project folder for later.
