Joe Albano on Apr 28, in Review 1 comments Share: So what could a new version add? Quite a lot, as Joe Albano found out The top-of-the-line is RX6 Advanced, which contains all the processing modules available for RX, including the new ones, for the most full-featured set of tools. RX6 Standard offers a slightly smaller subset of the full toolbox for a reduced price, but it does contain most of the key modules, including the ones RX is best known for like Spectral Repair.

For those on an even more modest budget, RX6 Elements is a smaller collection of basic repair tools, perfect for quickly cleaning up the most common flaws in typical recordings. A full comparison chart is available on the iZotope website.

Within the standalone, there are numerous features for enhancing workflow. Module Chains savable as presets, as are all module settings let the user assemble and quickly apply a string of modules, speeding up tasks that involve multiple processing.

RX6 offers additional workflow improvements: RX6 also introduces Composite View, a quick way to simultaneously process multiple files. While RX has always had batch processing capabilities via a dedicated window, Composite View is a more efficient way to temporarily group all open files together and apply processing to them all at once.

While there are a few common sense restrictions, it could speed up workflow for many tasks that need to be performed across multiple bits of audio. Some of these have incremental improvements – De-click, De-plosive, Voice De-noise, Ambience Match, Deconstruct and Center Extract all benefit from tweaks to their engines I particularly noticed the difference in De-click.

To this already comprehensive collection of audio tools RX6 has added several new Modules: De-ess provides settings for fine-tuning the frequency and speed of the de-essing, and it also offers a new Spectral De-essing mode, which applies spectral analysis and processing to the task of isolating and eliminating harsh sibilance. This can potentially make for more effective de-essing, with controls that allow the user to shape and tilt the spectral character of the sibilance, for more natural results.

The new Breath Control module adds options for both amount of breath reduction and sensitivity to breath sounds, which seemed to me to isolate breaths even more precisely than the older version. De-rustle is aimed at removing or reducing the rustling sound of clothing rubbing up a lavalier mic.

With a couple of files I threw at it, De-rustle was able to deal successfully with even fairly intrusive noise. A nice feature is an Ambience Preservation control, which allows De-rustle to remove rustling sounds while leaving other possibly desirable ambient sound intact. With a couple of torture-test files I threw at it that suffered from especially loud wind noise, De-wind acquitted itself admirably – it should have no trouble with more typical subtle wind problems.

A Fundamental Recovery control helps to restore any fullness in a voice lost to more aggressive processing, and Artifact Smoothing a control common to many modules helps to mitigate any hint of the watery-sounding artifact that sometimes accompanies this kind of FFT-based audio processing. Dialog Isolate This ambitious module lets you isolate a voice from background sound in a recording, or even vice-versa – pull a voice out of a recording, leaving just background sound or music.

Once again, unlike the existing Voice De-noise Module, Dialog isolate is tuned to be more effective with irregular background sound, rather than the regular noise the De-noise modules are designed to address. And it works surprisingly well. I was able to substantially reduce the level of some especially intrusive background noise subway train going by, loud voices is an ambient room , drawing out the primary voice until the background was, if not completely gone, largely unnoticeable; with less egregious examples of background sound, Dialog Isolate should be able to fully eliminate the undesirable noise.

De-bleed Finally, the new De-bleed module addresses the familiar issue of leakage, or bleed. Acoustic leakage, from other instruments in a live session, can also compromise the integrity of a track. De-bleed requires two files to do its thing: For example, in a scenario with, say, an acoustic guitar recording that was cut to a click track in headphones, the guitar, naturally would be the Active track, and the original click track the Bleed Source.

With a recording of a singer with bleed from a rough mix, the mix itself would be the Bleed Source. Both files must be loaded into RX6 currently, De-bleed only works in the standalone version , and to be most effective, they need to be time-aligned. When I tested this, I bounced down the appropriate section of a leaked mix and lined it up with the vocal which was an overdub in the DAW, and then brought both files into the RX6 Advanced application.

And it worked! And Dialog Isolate and De-bleed really do take audio repair to the next level. RX6 Advanced: Powerful collection of cutting edge tools for audio repair Cons:

Behind the Gear

They are the go-to processing effects for many post-production engineers and editors. That being said, it may be argued that releasing annual or even biennial paid updates without significant improvements is a bit exploitive. Many developers are guilty of this and sadly, this approach is integral to their business model and to the financial detriment of a loyal customer base. So when RX7 came out, I was immediately suspicious as to the true value and necessity of yet another update. But as I soon discovered, RX7 represents a significant advancement and builds on the areas of artificial intelligence and machine learning in which iZotope seems to be leading the way with other offerings such as the Neutron and Ozone bundles. New Features The Repair Assistant detects problems and suggests three ways to repair the problems, giving you a choice of repair processing effects chains that can be auditioned prior to rendering.
