iZotope RX 5 De-noise

iZotope RX 5 De-noise is an Audio Unit plugin, not a standalone application, so it is not updated independently. Instead, you must update the RX 5 suite itself through iZotope's Product Portal installer, which is the official distribution channel for all iZotope audio plugins. Visit the iZotope website, log in to your account, and use the Product Portal to download and install the latest version of RX 5. This will update all plugins in the suite, including the De-noise module, to their current builds. Be aware that iZotope has released newer versions of RX since version 5 (notably RX 9 and later), but if you are licensed for RX 5, the Product Portal will ensure you have the latest compatible build for that version. Check whether RX 5 supports native Apple Silicon—if your current build is Intel-only and a native version is available through the same installer, the newer build will offer better performance on M-series Macs. You have until September 2028 (when Apple removes Rosetta 2 in macOS 28) to ensure all your plugins are running native builds if you plan to upgrade to that macOS release.
