Stem separation, without leaving Premiere
Most stem separators mean exporting your audio, running it through a separate app, then re-importing the results and hoping the sync still lines up. StemForge skips all of that. Drop a track onto the panel and it separates right there in your project.
Illustration
Full mix
4-stem separation
Vocals, drums, bass, and other. This is the default model, built for speed.
6-stem separation
Adds guitar and piano as their own stems, for finer control when you need it. It runs slower than the 4-stem model.
Processed locally
Separation runs on your Mac through the StemForge companion app. Your audio never leaves your computer.
Questions
Why separate stems inside Premiere at all?
Bringing a drum hit in late, ducking a vocal under dialogue, stripping a track back to just guitar for a quieter moment. All of that is easier when the stems are already sitting in your bin, synced to your timeline, instead of living in a different app.
What file types can I drop in?
Any audio file Premiere can already import. Music, dialogue, SFX: if it has sound, StemForge can try to separate it, though results are naturally cleanest on music with distinct vocal, drum, bass, and instrument parts.
Does it work with DaVinci Resolve?
Not yet. StemForge today is a Premiere Pro plugin only.
Also need the tempo or key? See BPM and key detection.
