iZotope RX™ is the most complete audio restoration product on the market, a unique standalone application designed from the ground up to combat a range of audio problems. In addition to unique workflow features designed to help you get the best results, RX's powerful tools can do processing that plug-in based restoration products simply cannot do. This paired with completely new processing technology results in cleaner, more natural sounding noise reduction and audio repair.

RX is ideal for audio restoration and archiving, recording and mastering, broadcasting and podcasting, video production, forensics, and any application that demands spotless results and a truly complete range of restoration tools.

RX's standalone application gives you an ideal environment for audio restoration tasks. But for those times when you want the power of RX in your favorite audio sequencer or editor, the RX plug-ins are just what the doctor ordered.

iZotope has spent the last four years developing novel methods for revitalizing noisy and damaged audio, and iZotope RX represents a new milestone in restoration technology.

RX's Denoiser uses techniques adapted from digital imaging to reduce artifacts introduced by noise suppression, leading to more natural results with fewer distracting artifacts.

RX's Spectral Repair module can intelligently re-synthesize corrupted or missing audio with striking results, even recreating details like the vibrato on a singer's voice or changes in pitch.

Many of RX's modules, like the Declipper, use advanced multi-band and multiresolution processing techniques to achieve impressive results.
