Izotope Rx: Splitting a mix into stems with Music Rebalance

Demo summary
The narrator uses the new Stem Split feature to separate a full track into voice, bass, drums, and other stems for individual processing.
Step-by-step
- Open the Music Rebalance module
- Adjust the sensitivity sliders for Voice, Bass, Drums, and Other stems
- Select a processing mode from Real Time, Better, or Best
- Click Process to generate the stem-separated views
- Select individual stem tabs at the top to view specific audio components
- Apply RX modules to individual stems as needed for targeted processing
Options
- Choose between Real Time, Better (offline), or Best (offline) processing modes
- Toggle visibility between individual stems or all stems together
Tips
- Use specific RX modules on isolated stems to fix problems that are harder to address in a full mix
- Zoom in on individual stem views to see finer details of the separated audio
Highlights
“this is really, really awesome. It completely creates a new view here at the top.”
