RX 9 Spectral De-noise
RX 9 Spectral De-noise is a VST audio plugin from iZotope that removes unwanted noise from recordings—hum, hiss, room noise, and other stationary or slowly-varying background sounds—while preserving dialogue, music and other programme material. It is commonly used by podcast producers, voiceover artists, video editors, music producers and audio post-production professionals in digital audio workstations (DAWs) like Logic Pro, Cubase, Reaper and others that support VST plugins. The plugin is part of iZotope's RX 9 suite of audio restoration tools.
AI Recommendation
1 suggestionRX 9 Spectral De-noise is a VST plugin, not a standalone app—it runs inside your DAW and is updated through iZotope's own product management tool, not through the App Store or a generic vendor download. To get a native Apple Silicon build (if available) or to check for updates, use the iZotope Product Portal, which you can access by launching your iZotope account page or by opening the iZotope Product Portal application if it is already installed on your Mac. Log in, navigate to your RX 9 license, and download the latest version from there. The iZotope Product Portal will serve you the native Apple Silicon build automatically if you are on an Apple Silicon Mac and a native version is available for your iZotope RX product. If you installed RX 9 before native Apple Silicon support was added, re-download the installer from the iZotope Product Portal to get the native build on your M-series Mac. Your DAW does not need any special configuration—once the native plugin is installed, it will be available in your DAW's plugin browser immediately. As of May 2026 there is still time before macOS 28 removes Rosetta support in September 2028, but it is worth checking the iZotope portal soon to confirm a native build is available and to pull any pending updates.
