Izotope Rx: Real-time spectral editing in a DAW via ARA

IIzotope RxTry it →Watch full video →Mastering․com ·

Demo summary

The demonstrator uses the RX 12 Spectral Editor plugin inside Studio One to perform non-destructive plosive removal and S-attenuation directly on the timeline.

Step-by-step

  1. Add the RX Spectral Editor plugin to the audio file on the DAW timeline
  2. Select a specific frequency area, such as a plosive or sibilance, using the spectral view
  3. Choose a processing mode like Attenuate or Replace from the top menu
  4. Adjust the processing strength or gain as needed
  5. Click Render within the DAW to commit the edits to the waveform

Options

  • Attenuate
  • Replace
  • Gain
  • De-click
  • De-hum

Watch out for

  • If you have highly particular problems or need specific RX modules, you must use the standalone application instead of the real-time editor

Tips

  • Use the Replace function to discard a selection and reinterpret data based on surrounding frequencies
  • Use this plugin workflow to avoid dragging files into the standalone RX application for quick edits
  • Stay inside your DAW environment to maintain workflow speed while performing spectral repairs

Highlights

“this is for really quick on the-fly editing that happens in real time”
