iZotope RX

What is iZotope RX?

iZotope RX is the industry-standard audio repair and restoration suite, widely used in film, TV, podcasting, and music production. For filmmakers, RX is a lifesaver for cleaning up problematic dialogue, removing unwanted noise, and salvaging audio that might otherwise be unusable.

RX works as both a standalone application and a plugin suite inside your DAW or NLE. You can visually edit audio in a spectrogram view, identify issues (hiss, hum, clicks, wind noise, plosives), and use RX’s intelligent modules to fix them with surgical precision. It’s like Photoshop for audio.
