ntegrate RX with Live Without Melting Your Processor

iZotope’s RX is legendary for audio repair, but it’s also infamous for crushing your CPU when used as a plugin inside Ableton Live. Want the power of RX without glitching your session? Here’s a smarter way: use it as a standalone editor—directly from Ableton’s browser. This simple hack can save your CPU, your session, and your sanity.

Step 1: Set RX as the Default Sample Editor

• Open Ableton Preferences (Cmd + , on Mac / Ctrl + , on Windows)
• Go to File/Folder > Sample Editor
• Click Browse, navigate to iZotope RX, and select it
• Now RX is your go-to for audio sample editing directly from Live

Step 2: Editing in RX from Ableton

1. Duplicate the sample in Live with Cmd + D to protect the original
2. Consolidate the duplicate with Cmd + J to make it editable
3. Double-click the clip and press the Edit (pencil) icon
4. RX opens as a standalone app with your sample loaded and ready
5. Perform edits (e.g., breath control, de-clicking, etc.)
6. Once done, choose File > Overwrite Original File in RX

Your edits are now live inside Ableton, and you’ve avoided:

• CPU spikes
• Playback glitches
• Crashed sessions

Bonus Tip: Always Consolidate First

Consolidating ensures RX edits are applied to a clean, new file. This keeps your project organized and non-destructive. Always work on a duplicate.
