RX 6 De-ess
RX 6 De-ess is a professional de-esser audio plugin for iZotope's RX suite, designed to reduce sibilance and harsh frequencies in vocal recordings, dialogue and other audio sources. It operates as a VST plugin and integrates with digital audio workstations (DAWs) like Logic Pro, Cubase, Reaper and others. The plugin is part of iZotope's RX 6 toolkit, a suite of restoration and audio-cleaning tools used by audio engineers, podcast producers, post-production facilities and music producers.
AI Recommendation
1 suggestionRX 6 De-ess is a VST plugin component, not a standalone application, so it cannot be updated directly from the App Store or a generic download page. Instead, update the plugin through iZotope's Product Portal, which manages all RX 6 and later plugins across your system. Open the iZotope Product Portal on your Mac, log in with your iZotope account, locate RX 6 De-ess, and download the latest version from there — the installer will deploy the native Apple Silicon build if your Mac is M-series. If you installed RX 6 via a direct installer rather than the Product Portal, visit izotope.com, log into your account, and download the latest RX 6 update, which will include a native VST build. iZotope has shipped native Apple Silicon support in RX since version 9, so updating to the latest RX 6 build will ensure the De-ess plugin runs natively on your Mac without Rosetta translation, delivering better performance and lower CPU usage.
