Audio Repair and Separation for Music and Post Production
Used on countless albums, movies, and TV shows to restore audio from problematic to pristine condition, RX 10 Standard is a complete toolkit for audio cleanup. Find and repair issues with the new Repair Assistant plug-in, instantly remove hum and interference with dynamic De-hum, rebalance your mix and create stems with Music Rebalance, and clean up unwanted sounds directly in Logic® using the Spectral Editor built on ARA. Use the standalone audio editor or as plug-ins inside your favorite DAW or NLE to surgically improve any recording.
The Smart Solution for Clear Audio
Trusted by professional audio engineers to quickly and reliably deliver clean sound
Things break. So does audio. Recorded sound is rarely perfect – in fact, it’s often in really bad shape. That’s why you need RX, the award-winning audio repair suite that helps restore, clean up, and improve recordings in post-production, music, and content creation.
Built on decades of iZotope research, RX 10 is the most intuitive and intelligent version we’ve ever made. From analyzing audio capture and production issues to providing processing solutions, RX speeds up your editing workflow, salvages poor audio takes that were once unfixable, and delivers reliably clear sound quality.
Whether you are editing a podcast, recording a full band, or working on a blockbuster movie, RX 10 enables you to captivate audiences by bringing out the best in recorded audio.

If you’re new to audio repair, or you just want to save time, try the new Repair Assistant Plug-in, which uses machine learning to find and fix audio issues quickly without leaving your DAW. The Assistant automatically recognizes specific problems and intelligently proposes a repair chain that you can modify to your liking with easy-to-use dials. More than just an upgrade of the previous Repair Assistant, this plug-in was built from the ground up.
Navigate through words.
Even if you love spectrograms as much as we do, navigating long dialogue files can be time-consuming, especially when seeking specific events in a recording. Now you can see what you hear with the new Text Navigation function. It analyzes dialogue and displays a text transcription above the spectrogram that’s in sync with the corresponding audio. So you can now search for specific words in an audio file and also select and edit the recording using text. [This navigation feature will only be available in English for RX 10.]
Dynamic Adaptive Mode in De-Hum [Standalone Editor]
Adapt to the noise.
Save time removing unwanted hum with the new Dynamic Adaptive Mode in De-Hum. Get rid of hums and buzzes on the fly, without having to spend time learning the noise profile of your audio. Eliminating electromagnetic interference or other complex noise that changes pitch can now be done automatically without sacrificing quality.
First Time User Experience
Is it THAT simple?
RX is complex. That’s why we added the First Time User Experience, an interactive tour to guide you through the software. Whether you’re new to RX or catching up with the latest version, we have a tour for you.
Additional enhancements in RX 10
Make smoother edits with improved Selection Feathering, which now also works in the frequency domain.
Native M1 Support – Supported on Intel Macs & Apple silicon Macs (Apple M1 chips) in Rosetta 2 and native.

Repair Assistant Plug-in (New)
The new assistant plug-in automatically recognizes the problem and proposes a repair chain, tweakable with a couple of easy-to-use dials. Rather than simply making a plug-in version of the current Repair Assistant, this plug-in was built from the ground up.
