Mix Audio
Blend multiple audio tracks with individual volume control.
Overview
The Mix Audio node layers multiple audio tracks together with per-track volume control. Reorder tracks via drag-and-drop and adjust each track’s volume from 0% to 200%. The output is a single mixed audio file.

Best Practices
- Keep voiceover at 100% and reduce background music to 30-50% for clear speech
- Use volume above 100% sparingly — it can introduce clipping/distortion
- Layer tracks intentionally: voice first, then music, then effects
- Preview the mix before connecting to downstream nodes
Common Use Cases
- Layer voiceover on top of background music
- Combine multiple sound effects with a music track
- Mix dialogue with ambient audio for cinematic scenes
- Create audio beds from multiple generated audio tracks
Tips
- Connect to Merge Video & Audio after mixing to add the combined audio to video
- For simple volume adjustment of a single track, use Adjust Volume instead
