RX 4 is the result of iZotope’s collaboration with working professionals to identify new ways of improving workflows. They’ve translated these insights into technologies that address common needs and reflect the way people naturally want to work. RX 4 enhancements take you beyond mere audio repair—letting you truly enhance and transform your audio.

RX’s intuitive UI makes it appropriate for Hollywood post-production studios and leading sound editing facilities as well as bedroom studios. And now, audio and video editors of all types can work more intuitively than ever thanks to a redesigned interface—clean and approachable for first-time users, yet familiar for existing users.

Whether you use it as a standalone application or plug-in, RX 4 seamlessly integrates with your audio or video editor. A suite of automatic, intelligent modules reduce manual tasks in your audio production workflow, freeing you up to focus on creative experimentation. And for professionals who need to quickly deliver quality results, RX 4 Advanced offers even more specialized post production tools.

Unlock a more detailed visualization of your audio—and see what your waveform won’t show you—with an informative spectrogram display. Then, edit your audio like you would edit an image using drawing tools like lasso, brush, magic Wand. Replace unwanted sounds and fill gaps in recordings with Spectral Repair, which intelligently resynthesizes audio to restore a seamless listening experience. Easily finesse your sound with dedicated audio enhancement modules like EQ, Gain, and Channel Ops.
