iZotope RX 11

iZotope RX is the audio restoration suite that post-production engineers reach for when nothing else will save a take. The interface centers on a spectrogram you can edit visually, painting out individual clicks, hums, mouth noise, and background chatter while leaving the wanted dialog intact.

For podcasters, that means you can rescue a guest recorded on a laptop mic in a coffee shop without throwing out the episode. The Repair Assistant uses machine learning to scan a clip and propose a chain of modules with intensity sliders, which is the fastest way in for people who don't want to learn every tool.

Higher tiers add Dialogue Isolate for pulling voice out of bleed, Music Rebalance, Spectral Recovery for restoring frequencies stripped by Zoom compression, and Multiple Speaker Detection for applying per-voice processing. There are three tiers, with Advanced aimed at full-time engineers and Elements covering the basics for hobby shows.

RX 11 Standard runs around $418 retail, with sale prices typically in the $223-$279 range. iZotope released RX 12 in 2026, with upgrades from any RX Standard starting at $129. If you're starting fresh, RX 12 is the right purchase; RX 11 is one version back but still widely supported. Either way, if your show involves remote guests or field recordings, RX pays for itself the first time it saves an episode.
