Denoiser
Using new techniques based on image processing technology, RX's Denoiser module is designed to remove steady-state noise like tape hiss, camera motor noise, environmental noise, and more. While the module runs in automatic mode, it can also be trained with a sample of the noise - very cool.

Spectral Repair
This module removes intermittent noises and can intelligently fill in gaps in an audio file. Even if what's missing includes changes in vibrato or pitch, Spectral Repair can learn from the audio surrounding a section and resynthesize the missing audio.

Declipper
Declipper can remove analog and digital overload distortion and actually rebuild damaged peaks in clipped audio, effectively resurrecting previously unusable tracks.

Hum Removal
Wiring problem? No problem. RX's Hum Removal can isolate electrical hum as well as any resulting harmonics. Hum Removal offers a 50Hz and 60Hz hum removal, but can also operate in a Free Mode, letting the user remove hum from any frequency necessary.

Declicker
Especially useful when archiving, Declicker can suppress the familiar pops and crackles from vinyl and record masters as well as similar digital impulse noises.

Detailed spectrogram display
RX offers an extremely crisp and detailed spectrogram display, making it easy to spot clipping, buzz, and any other audio problems with a mere glance.

Selective Processing
With RX, you can select by time and frequency and easily isolate the problematic noise. Queued Processing allows you to audition multiple module settings side by side.

Undo History
Even after saving, iZotope's RX allows you to revert back to earlier states.

iZotope RX is a professional and affordable audio restoration suite.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent.

If you have other balances on your account, this payment will be added to any other minimum monthly payments.
