RX 12 Spectral Editor
RX 12 Spectral Editor is an Audio Unit (AU) plugin from iZotope (now part of Native Instruments) that provides spectral analysis and editing capabilities for audio production. It integrates with Digital Audio Workstations (DAWs) like Logic Pro, Cubase, and other AU-compatible hosts, allowing users to visualize audio waveforms in the frequency domain and surgically remove unwanted sounds, background noise, clicks, pops, and other audio artifacts. The spectral editor is used by audio engineers, podcast producers, video editors, and musicians for restoration, mixing and mastering workflows.
AI Recommendation
1 suggestionRX 12 Spectral Editor is an Audio Unit plugin, not a standalone application, so it is updated through iZotope's plugin management system rather than through the App Store or a generic download. To get a native Apple Silicon build if one is available, visit the iZotope Product Portal (your iZotope account dashboard) or use the iZotope installer to update RX 12 and all its component plugins to the latest version. iZotope has shipped native Apple Silicon builds of RX since version 9 (released in 2021), so updating through the iZotope Product Portal will automatically serve you a native build on M-series Macs. If you do not yet have the iZotope Product Portal set up, visit izotope.com, sign in with your account, and follow the installer prompts. After installation, the AU version of RX 12 Spectral Editor will be available to your DAW's plugin scanner, and you may need to rescan plugins in your host application (Logic Pro, Cubase, etc.) for it to appear in the plugin browser.
