Hum Removal

The RX Hum Removal module 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.

Declipper

The RX Declipper can save previously unusable recordings by removing analog and digital overload distortion. Declipper uses advanced multiband processing to actually rebuild damaged peaks in clipped audio.

Spectral Repair

The RX Spectral Repair module 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.

Advanced Spectrogram

The RX software’s unique spectrogram display can represent audio with an unparalleled level of detail and sharpness. RX's spectrogram uses newly developed technology to attain the greatest time and frequency resolution available. Use the spectrogram display to identify clipping, buzz, intermittent noises and other problems at a quick glance.

Declicker

The RX Declicker can automatically suppress clicks, crackles and pops as well as similar digital impulse noises. Ideal for cleaning up audio archived from vinyl, cylinders and record masters, Declicker also features a manual mode for isolating and repairing hard-to-fix clicks and pops.

Denoiser

The RX Denoiser module 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.

Interface and Workflow

iZotope RX was designed from the ground up with efficiency in mind. Time-saving workflow features include selective processing, which 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.
