Hum Removal

RX Hum Removal uses precise filtering to isolate electrical hum as well as any resulting harmonics. In addition to 50Hz and 60Hz hum removal, a Free mode allows for hum removal at other frequencies.

Spectral Repair

RX Spectral Repair can remove hard-to-fix intermittent noises and even intelligently fill in gaps in an audio file. Spectral Repair can learn from the audio surrounding a selection and resynthesize missing audio, even if the content includes changes in pitch, vibrato and harmonics.

Denoiser

The RX Denoiser is designed to remove broadband and steady-state noise including tape hiss, environmental background noise, camera motor noise, buzz and more. Denoiser can be trained with a sample of noise, or it can run in automatic mode. Denoiser uses special techniques based on image processing technology to achieve natural sounding results with a minimum of artifacts.



Standalone Operation

iZotope RX was designed from the ground up with efficiency in mind. In standalone mode, RX features time-saving workflow enhancements—including selective processing, a function that allows you to select by time and frequency to apply processes with surgical precision. You can also send multiple settings of the same module into the Compare Settings window and audition them side by side to choose the best result. Use the Batch Processing option to automate processing on a single file or on multiple files using different modules and tools within RX. There’s also a convenient Undo History that allows you to quickly step back to earlier states.
