How StemForge works
StemForge is a desktop companion app and a Premiere Pro plugin working together. The plugin is the panel you use inside Premiere; the companion app does the actual audio processing in the background. Everything runs locally, and your audio never leaves your Mac.
Step 1
Drop in a track
Drag any audio file onto the StemForge panel in Premiere Pro, or browse to it. It works on dialogue, music, SFX, anything with sound.
Step 2
Analyze
StemForge detects the track's BPM and musical key automatically, so you know what you're working with before you touch anything.
Step 3
Separate into stems
Split it into vocals, drums, bass, and other. Or switch to the 6-stem model to also pull out guitar and piano.
Step 4
Render a matched version
Set a target BPM or key and render a time-stretched or pitch-shifted version to match your edit.
Step 5
Import straight into your bin
Click Import next to any result to bring it directly into the active Premiere project. No exporting, and no round-tripping to another app.
Bring it all into one Premiere workflow.
