iZotope RX 5 De-hum
iZotope RX 5 De-hum is an Audio Unit (AU) plugin for macOS that removes persistent hum and noise from audio recordings. It is part of iZotope's RX 5 software suite, a professional audio restoration and enhancement toolkit used by audio engineers, podcasters, voice-over artists, and post-production professionals to clean dialogue, music, and field recordings. The De-hum plugin specifically targets 50 Hz and 60 Hz mains frequency noise and their harmonics. To use this plugin, you need a compatible host application such as Logic Pro, GarageBand, Adobe Audition, or another AU-compatible audio editor or DAW.
AI Recommendation
1 suggestioniZotope RX 5 De-hum is an Audio Unit plugin, not a standalone application, so it is updated through iZotope's own product manager rather than through a host app's plugin browser or the App Store. To ensure you have a native Apple Silicon build of this plugin, use the iZotope Product Portal (iZotope's account and download manager) to update RX 5 to the latest version. iZotope shipped native Apple Silicon support for RX and its plugins starting with RX 9 (released in 2021), so if you are running RX 5, upgrading to RX 9 or later will give you native arm64 performance and future-proof you before macOS 28 removes Rosetta 2 in September 2028. If you prefer to stay on RX 5, contact iZotope support to confirm whether your installed version includes a native AU component; older RX 5 releases may still be Intel-only.
