RX 7 De-ess
RX 7 De-ess is a VST audio plugin from iZotope that specializes in reducing sibilance and harsh high-frequency artifacts in vocal recordings and other sources. It is designed for use within digital audio workstations (DAWs) and audio production software that support VST format. De-essing is a standard post-production tool in music mixing, podcasting, voiceover work and speech processing. The plugin integrates into the host DAW's mixing interface and is typically used during the mixing or mastering phase to tame problematic 's' and 'sh' sounds in recordings.
AI Recommendation
1 suggestionRX 7 De-ess is a VST plugin component, not a standalone application, and is updated through iZotope's own installer and product management tool, not through your DAW or the App Store. To get a native Apple Silicon build of this plugin, download and run the iZotope Product Portal (or iZotope Installer if you have an older version) from iZotope's website, sign in with your account, and ensure your RX 7 suite is updated to the latest version available. iZotope began shipping native Apple Silicon builds of the RX suite starting with RX 9 (released in 2020), so the latest RX 7 builds should include a native arm64 variant alongside the Intel build. Your DAW itself must also be running a native build and configured to scan VST plugins in the correct architecture folder — verify that your DAW is set to native Apple Silicon mode so it loads the arm64 version of the plugin rather than the Intel version under Rosetta. If you are still running an older RX 7 build from before native support was added, updating via iZotope's Product Portal will resolve that.
