RX 9 De-ess is an AAX audio plugin for iZotope's RX audio restoration suite, designed to remove excessive sibilance ('ess' sounds) from vocal and speech recordings in post-production. It runs within Avid Pro Tools as a plugin and is used by audio engineers, podcast producers, voice-over editors and music producers to clean up vocal tracks. A native Apple Silicon build has been confirmed running on Macs in the Rosetta Check community.
AI Recommendation
1 suggestionRX 9 De-ess is an AAX plugin that runs inside Pro Tools. To get the native Apple Silicon build, you need to take two steps. First, ensure your Avid Pro Tools host is on version 2023.6 or newer — this is the minimum version that supports native AAX plugins on Apple Silicon; earlier versions only load Intel plugins. Second, update iZotope RX itself through the iZotope Product Portal, which will install the native Apple Silicon version of the plugin. Once both the host and plugin are native, Pro Tools will automatically detect and load the native RX 9 De-ess instead of the Intel build under Rosetta. If you installed RX via iLok License Manager, also check that your iLok account is set to the latest RX 9 build. After updating, Pro Tools will recognize the native plugin the next time you launch the application or refresh the plugin cache.
