Music Gear Review: iZotope RX 5 Plug-in Pack

The iZotope RX 5 Plug-in Pack’s four audio repair plug-ins are for cleaning up and, at the extreme, rescuing corrupted audio recordings. Ported from iZotope’s RX 5 Audio Editor, the four VST/AU/AAX/RTAS audio plug-ins are: De-click, De-hum, De-clip, and Dialogue De-noise. They work within your preferred audio or video editing software as real-time processors or as clip- based processes.

The plug-ins can be used to remove clicks, crackles, hum, fix distortion caused by over loading (clipping) and remove unwanted wideband noise from audio. I tested all four plug-ins as AAX processors in Pro Tools 12 HDX and found many uses within my music mixes. Beyond noise reduction, I discovered some happy accidents that were useful in my mix.

Dialogue De-noise has 64 “psycho-acoustically spaced band pass filters” that analyze the incoming dialog audio and automati- cally adjust for changes in the noise floor. De-clip automatically repairs “overs” that can happen in live recordings or in the studio with unexpected level jumps while recording. De-clip will fix clipping whether it came from analog tape or an overloaded A/D converter. The De-click processor worked transparently to remove short pops and ticks that happen in digital recordings. Lastly, De-hum will remove low frequency hum (usually 50 or 60 Hz) and up to seven harmonics above it.

An awesome collection to have at the ready when mixing, the RX Plug-in Pack is $129 MSRP.
