RX 7 De-ess
RX 7 De-ess is an AAX audio plugin for Avid Pro Tools that intelligently reduces sibilance (harsh high-frequency "S" and "SH" sounds) in vocal and speech recordings. It is part of iZotope's RX suite of audio restoration tools and is widely used by audio engineers, podcasters, music producers, and voice-over specialists to tame problematic sibilance without affecting the rest of the audio. The plugin integrates directly into Pro Tools and operates as a real-time or offline audio processor.
AI Recommendation
1 suggestionRX 7 De-ess is an AAX plugin for Pro Tools and is updated through iZotope's product management system, not through Pro Tools itself. To get a native Apple Silicon build of this plugin, you will need to install or update iZotope's RX software suite through iZotope's official installer or the iZotope Product Portal. First, ensure that Pro Tools itself is running a current native build (version 2023.6 or newer) — older versions of Pro Tools do not support native AAX plugins. Then download and run the latest iZotope RX installer for macOS and let it update the AAX plugin files in Pro Tools' plugin directories. iZotope has shipped native Apple Silicon builds of RX since version 8, so updating RX will automatically give you native AAX plugins. Note that you may need to rescan Pro Tools' plugin cache (File → Preferences → Plug-In Manager → Verify Plug-Ins) after installation so Pro Tools recognises the native version.
