Repair recipes

Start with the artifact, not a retake

Most damaged takes are recoverable if you name the problem first. Listen once, decide whether you hear broadband noise, a tone, clicks or clipping, and reach for the one module built for it — before stacking processing you cannot undo.

How these guides are checked

Guides are researched from iZotope’s manual, release notes and support articles, and each fact that can change is linked where it is used. When versions or editions behave differently, the guide says which one it describes. When iZotope changes a module, the guide is revised and its date moves.

Questions readers ask

What is iZotope RX used for?

RX is an audio repair and restoration suite: it removes noise, hum, clicks, clipping and other artifacts from dialogue, music and location recordings, working as a standalone editor and as plugins inside a DAW or NLE.

Do the guides cover my RX version?

Each guide names the version it was written against and flags where older editions behave differently. Module names and layouts shift between releases, so the version scope is stated up front rather than assumed.

Where should a beginner start?

Start with the spectrogram: once you can read what noise, tone and speech look like, every module makes sense. The Start here hub walks that path before any repair recipe.

Is izotoperx.net affiliated with iZotope?

No. This is an independent publication. It is not affiliated with, endorsed by, or sponsored by iZotope or Boris FX, and guides say plainly when a built-in tool or a cheaper edition is enough.
