iZotope RX
Industry-standard audio repair and dialogue restoration software for post production
About iZotope RX
iZotope RX is a desktop audio repair suite with a standalone spectral editor and plugins for DAWs and video editors. It uses machine-learning modules such as Dialogue Isolate, Spectral De-noise and Dialogue De-reverb to remove noise, reverb, clicks, hum and clipping from dialogue and music. RX 12 is sold as Elements, Standard and Advanced editions; iZotope has been part of Boris FX since July 2026.
Pros & Cons
Pros
- Deepest set of dialogue repair modules of any single product, from Dialogue Isolate to spectral repair
- Spectral editor lets you remove one-off noises surgically without processing the whole clip
- Plugins run inside Premiere Pro, DaVinci Resolve, Final Cut Pro and every major DAW
- Perpetual licenses with no recurring fee
- Processing runs locally, so footage never leaves your machine
- Used on major film and TV productions, so editors and mixers already know it
Cons
- Steep learning curve; the best results come from combining several modules
- Advanced edition costs $1,399, and key film tools like Scene Rebalance are Advanced-only
- Desktop software only (Windows and macOS), with no web or mobile version
- Independent 2025 dialogue shootouts no longer placed Dialogue Isolate first in every noise category
