Izotope RX
The industry-standard toolkit for fixing broken audio
What it is
About Izotope RX
iZotope RX is used across post-production, broadcast, podcasting, and music to clean up dialogue and recordings — removing background noise, hum, clipping, reverb, and clicks using spectral repair and machine-learning-assisted modules. It's a go-to tool for making unusable location or archival recordings broadcast-ready, and is standard in film and TV post-production and forensic audio work.
