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

Every guide states which RX version and edition it was written against, links the primary source for changeable facts, and keeps destructive steps behind a rendered copy of your file. When iZotope changes a module, the guide is revised and the revision 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.
