AI Stem Separation
AI Dialogue Isolation
Isolate dialogue from background music and effects with AI — clean movie, video, and podcast speech.
About this tool
Dialogue isolation targets spoken word in mixed media, pulling it away from score, SFX, and room tone so the line is clear.
It is a specialized form of source separation tuned for intelligibility rather than musical purity.

FAQ
- Keeps the music out?
- It strongly attenuates score and SFX, though a faint bed may remain under loud moments.
- Works on video files?
- Yes — the audio track is processed; the video container is preserved on export.
- Good for accents?
- Separation is language-agnostic, so any accent separates as long as it is the dominant speech.
