iZotope RX is professional audio-repair software used to remove noise, hum, clicks, clipping, reverb and other unwanted artifacts from recordings. It ships as a standalone spectral editor plus DAW/NLE plugins, aimed at podcasters, musicians, dialogue editors and film/TV/game-audio post teams who need to fix genuinely damaged audio, not just polish clean audio. RX is sold as a one-time perpetual license across three tiers — Elements, Standard and Advanced — starting at $99, with a monthly subscription bundle also available instead of buying outright.
Who builds it
iZotope has built audio-restoration software since the early 2000s, and RX's technology has been credited with an Academy Award and two Emmy Awards for its contribution to film and TV post-production. In July 2026, Boris FX acquired iZotope, separating it from the Native Instruments group it had been part of since 2024; both companies say existing RX licenses, subscriptions and support continue unchanged under the new ownership. The core workflow: open a damaged file in the standalone RX Audio Editor (Standard and Advanced) or insert an RX plugin into a DAW/NLE track, then use the automatic Repair Assistant or manual spectral tools to find and remove noise, hum, clicks and reverb on a spectrogram.
Core features
- Repair Assistant: an ML-driven tool that analyzes a file and proposes an automatic fix chain, so non-specialists get a quick repair.
- Spectral Repair and Spectral De-noise: click-and-drag repair directly on the spectrogram display, from the Standard tier up.
- Music Rebalance and Dialogue Isolate: neural-net stem separation that pulls vocals, dialogue, music and effects apart for independent processing (Advanced tier).
- Scene Rebalance and Stems View, new in RX 12: let post engineers independently adjust dialogue/music/effects levels and work stem-by-stem.
- A large module set — De-click, De-clip, De-hum, De-reverb, De-wind, De-bleed, De-ess, Breath Control and 40+ other single-purpose repair tools across the suite.
- Runs standalone or as AAX, AU, VST3 and ARA2 plugins inside Pro Tools, Logic Pro, Ableton Live, Cubase, Premiere Pro, DaVinci Resolve and other DAWs/NLEs.
Pricing
- RX 12 Elements — $99 one-time: 6 plugins (De-click, De-clip, De-hum, De-reverb, Voice De-noise, Repair Assistant), no standalone editor.
- RX 12 Standard — $399 one-time: adds the standalone RX Audio Editor plus Spectral Repair/De-noise, roughly 18 modules total.
- RX 12 Advanced — $1,399 one-time: 50+ tools including Scene Rebalance, Music Rebalance, Stems View and Dialogue Isolate.
- RX Post Production Suite 9 — $1,799 one-time: bundles RX 12 Advanced with Neutron 5, Nectar 4 Advanced, Insight 2, Equinox and more.
- Alternative: iZotope Plus subscription from $12.50/month includes RX 12 Elements; iZotope Pro includes RX 12 Standard (price unpublished) — both with a 7-day free trial, not a permanent free tier.
- No permanent free version of RX itself; the trial runs at full functionality for 10 days, then continues in demo mode with periodic silence and export/save disabled. Check the current pricing page, since iZotope runs frequent sales.
Who it's for
Podcasters, musicians, dialogue/ADR editors and film/TV/game-audio post teams repairing recordings with real problems — noise, hum, clipping, reverb, wind, mic bleed — that one-click cleanup tools can't fully fix. Elements suits budget in-DAW cleanup; Standard is the common choice for freelance engineers wanting the full spectral editor; Advanced (or the Post Production Suite) targets professional teams handling dialogue, ambience and multi-stem film/TV mixes. For a quick "make my podcast sound decent" job, cheaper AI tools may be enough — RX is built for audio that's seriously damaged and needs surgical, manually-guided repair.
