iZotope RX 2 Denoiser
iZotope RX 2 Denoiser is an Audio Unit (AU) plugin for macOS that removes background noise, hum, and unwanted audio artifacts from recordings. It is part of iZotope's RX suite and integrates with compatible Digital Audio Workstations (DAWs), audio editors, and other AU-hosting applications such as Logic Pro, GarageBand, and other professional audio tools that support Audio Unit plugins. The plugin is used by audio engineers, podcasters, sound designers, and musicians who need to clean up dialogue, field recordings, or other noisy source material.
AI Recommendation
1 suggestioniZotope RX 2 Denoiser is an audio plugin component, not a standalone app, and cannot be updated separately through the App Store or a generic download. To get a native Apple Silicon build, you must update iZotope's RX suite through the iZotope Product Portal, which is the official update channel for all iZotope plugins. Visit the iZotope Product Portal on your computer, log in with your iZotope account, and download the latest version of RX — this will install native Apple Silicon builds of all included plugins, including the RX 2 Denoiser AU. If you do not have an iZotope account, create one using your iZotope license code or serial number. Alternatively, if RX was installed via a previous standalone installer, visiting iZotope's main website and downloading the latest RX installer will also provide the native build. iZotope has shipped native Apple Silicon builds of RX 9 and later since 2021, so updating to a recent release will eliminate any reliance on Rosetta 2 emulation.
