### Full Description
Audio repair is a solved problem if you can afford to solve it well. [iZotope RX 11](https://www.izotope.com/en/products/rx.html?utm_source=musicianstack) is the suite that set the benchmark, and after more than a decade of iteration it remains the tool that dialogue editors, mastering engineers, and music producers reach for when recordings go wrong.
The core workflow centres on a standalone audio editor with a spectral display that lets you see and select individual sonic events — a cough buried under dialogue, a string squeak mid-take, a siren in the background of an interview. Once you have it selected, bespoke repair modules handle the rest: **De-noise**, De-click, De-clip, De-hum, De-rustle, Ambience Match, and more. The Repair Assistant module uses machine learning to diagnose problems automatically and propose settings, which means you can get to a clean result without knowing your way around every module.
RX 11 comes in three tiers. Elements is the entry point: six tools, no standalone editor, aimed at podcasters and beginners. Standard adds the full standalone app, 33 tools including Dialogue Isolate and Music Rebalance, ARA support, and the new Loudness Optimize and Streaming Preview modules. Advanced rounds out at 44 tools, adds the highest-quality offline processing for Dialogue Isolate, multi-band processing, and is the version post-production professionals use daily.
**Dialogue Isolate** is arguably the headline feature in RX 11: real-time vocal separation with simultaneous de-reverb, now available in Standard for the first time. It runs as a live plugin inside your DAW with low latency, which changes the workflow considerably compared to previous versions that required round-tripping audio through the standalone app. Music Rebalance handles stem separation for remixing or creating instrumentals, and its quality has improved significantly with the neural network upgrade in RX 11.
The new Loudness Optimize module is notable: it analyses your master and manipulates the signal to maximize perceived loudness after streaming normalization — operating within the LUFS algorithm rather than just hitting a target ceiling. Streaming Preview lets you audition how platforms like Spotify and Apple Music will process your file before you export.
Plugin formats are AU, AAX, and VST3, all 64-bit only. VST2 is not supported. ARA integration is available for Logic Pro (Rosetta only on Apple Silicon), Pro Tools, and Studio One, which means you can do spectral editing inline without leaving your session. Full native Apple Silicon support is confirmed on both Intel and M-series Macs, with the Rosetta caveat for ARA workflows in Logic. Confirmed DAW compatibility covers Logic Pro 12, Pro Tools 2025, Ableton Live 11 and 12, Cubase 15, Nuendo 15, Studio One 7, Reaper 7, FL Studio 25, Adobe Audition, Premiere Pro, DaVinci Resolve 19, and Reason 13.
Authorization runs through iZotope's own Product Portal (now under Native Instruments), with machine-based licensing. No iLok is required. Some users have flagged friction with the Native Instruments product portal setup, particularly on macOS after a fresh install.
A 10-day free trial of RX 11 Advanced is available without a credit card. iZotope runs sales frequently — Advanced in particular is worth waiting for if the full list price is a barrier. Upgrade pricing from previous RX versions is also available.
KVR Audio named RX the Favourite Audio Editor six consecutive years (2019 through 2024). Two Engineering Emmy Awards and an Academy of Motion Picture Arts and Sciences Scientific and Engineering Award sit on the record. It is used on the majority of major film and television productions as a matter of course.
For **music producers** specifically, the value case is narrower than for post-production. De-noise, De-click, and Music Rebalance are genuinely useful for fixing recordings and working with samples, but if your recordings are clean the suite can feel expensive for the use you get. The Elements tier at a one-time entry price is a reasonable starting point for music-only workflows.
