An Incredible Suite

The renowned RX suite just got a major update, with several new improvements and additions. iZotope RX7 is an absolute essential suite, no matter if you’re working on music, field recording, sound design or audio post production, it can save not only a lot of time (avoiding re-recording), but it can literally fix problems transparently in most cases. Noise, mouth clicks, lavalier rustle, hum, wind rumbles, digital clicks, crackles, plosives and breaths, as well as less exoteric operations like levelling, normalizing, resampling, and this on one or more files, on the whole audio file or just in a time or frequency selection. The scenarios in which RX can operate are countless, but what is important to note is that we have everything in the same workspace if we’re focusing on repair, or we can open single plugins in our DAW for fast fixes. RX7 plugins are now available as AudioSuite plugins too, and the family just got bigger, as we will see.

A great number of videos, and the new Repair Assistant, will make corrections even easier, showing you the essential techniques, problems and how to fix them. The different versions of RX also offer flexibility in terms of needs, price and use. RX is getting closer and closer to musicians, and the new Music Rebalance module is a demonstration of the attention iZotope pays to the different targets.

In this review we will focus only on the new elements, but if you’re new to the RX world, you might be interested in reading more about what is RX and its amazing modules in the two previous reviews on the Soundbytes Magazine website.

What’s New

As anticipated, the list is not short, starting from a light UI refinement, to multichannel support and, of course, entire new modules.

Pro Tools users now can enjoy Dialogue Isolate, De-rustle, Breath Control and the new Music Rebalance modules as AudioSuite plugins. AudioSuite is a Pro Tools format of audio plugins which can be used on a single audio clip or on multiple clips at once instead of on an insert track. The processing through AudioSuite plugins needs to render the processed files, replacing the clips we treated with new ones.

Multichannel is now supported up to 7.1.2 (10 channels) Dolby Atmos, meaning that you can process one or all the channels with the same module and in just one instance. Such a powerful new feature that will further speed up the work of audio engineers working on films or where multichannel audio is required.

Dialogue Isolate and De-Rustle modules’ performance has been enhanced, starting from the new Preview function for checking their operations on the go.

Another important new feature is the possibility to select a frequency range of action for the modules directly in the Module Chain. This truly gives extra power to the Module Chain, allowing to arrange even more specific corrections per single module.

New Modules

Let’s start from the new Dialogue Contour module, which is designed to shape and modify the pitch and inflexion of dialogue parts. Intonation and inflexion are obviously fundamental (not to mention that in some languages they have a distinctive function, and can alter the entire meaning of a word). In some languages, like Italian, for instance, intonation might distinguish an affirmative sentence from an interrogative sentence, because the position of the terms is the same in both cases. Linguistics apart, perfecting inflection before could involve micro pitch shifting or formant shifting using automation or external tools. Now we are just a few clicks away from our goal. Insert the module, isolate a section or the entire file and create your custom curve by adding, moving or deleting individual points, and smoothen the final result. Formant scaling is also available in order to shift specific resonances or attenuations in the spectrum, respecting the natural formants of the human speech.

Dialogue De-Reverb is the new module specifically designed for removing reverb from voice. RX also has a De-Reverb module, but the new one does not require to learn the reverb profile, and it is based on machine learning algorithms. Particularly useful both in audio post, if we don’t have the chance to get our interview in a proper room, or in music production, if we need to record vocals in a reverberant environment. Its controls include Sensitivity and Ambient Preservation in order to balance the result and to identify how much of the incoming signal can be considered as reverb.

Variable Time and Variable Pitch allow the user to select a portion of the audio file and design a custom shape for pitch or time variations in the same way we described for the Dialogue Contour module. What deserves attention here, is the incredible, crystalline audio quality of these tools. Not to mention that these can absolutely wink an eye to Sound Design. I tested Variable Pitch on an entire song, with both time changes and Preserve Time enabled (with the first, the module will behave like a Tape play head changing pitch and speed of the file), and I barely heard artifacts, even with generous pitch variations. Here, too, possible applications are countless, from extreme pitch shifting on raw sound sources to morph them into bizarre effects, or gentle shifts with time changes which reminded me of the old days of sampling material for musical purposes. Pitch Coherence and Transient Sensitivity controls appear on both the modules, allowing for timbre and transient preservation.

Izotope Rx7 Music Rebalance

Last but not least, the Music Rebalance module, which created a quite a stir when first announced. People are probably asking if it’s true that it can remove vocals from a song or an instrumental leaving just vocals. The answer is yes. Simply divided in Voice, Bass, Percussion and Other, Music Rebalance allows us to set the Sensitivity of the analysis, letting know the module how much of the incoming signal should be considered as Bass, Vocal, etc., and we can set the gain for each of the parts. Low Sensitivity values can reach precise results by completely muting tiny parts of other instruments that might come in the analysis, but at the cost of small artifacts, while if we are after complete clarity, higher values can eliminate glitches, but other instruments might end up in the result. Sometimes reverb can be an enemy of Music Rebalance, probably because of the long tails which can be confused with the voice or the behavior of other instruments. But despite some artifacts, Music Rebalance works very well and it is capable of extracting a cappella voices from an entire song which is more than useable.

Apart from the vocal extraction, Music Rebalance’s main role, I think, resides in other uses, like an intelligent way to give space to various sections, moving entire instruments inside or outside the mix. Or it can completely reshape a song with problems, and in this, Music Rebalance excels, especially for the idea of changing the balance of a track with just a few and intuitive parameters. When everything seems lost, and we probably are in front of a single WAV file, without the possibility of touching any fader in the DAW, it can save the day.

Repair Assistant

Probably the most interesting addition to the whole Suite, Repair Assistant can intelligently analyze an audio file, identify problems and suggest corrections. In the top right of the RX7 standalone interface, just click on the Repair Assistant tab to engage this tool. It is absolutely wonderful to have a personal assistant which will analyze and possibly speed up even more the work. Repair assistant will ask if the file contains musical, dialogue or other material, then starts the analysis searching for clipping, clicks, hum and noise. In the settings, we can also customize its analysis bypassing one of the problems, for instance, we can exclude the hum analysis.

Clever, fast and powerful, Repair Assistant is another magical element in RX that will make the entire suite even easier and quicker to use, and I personally love how smart plugins are becoming lately. Surely, this won’t mean that the human touch is completely bypassed, and the ability to identify problems, solve them, tweak the modules, is still required, but Repair Assistant can work as a huge “learn” function on the entire audio file, allowing us to complete a task in a matter of clicks.

There’s more, and this is another great proof of flexibility: if problems are found, Repair Assistant will purpose three different solutions, each of them containing a different module chain, so different modules arranged in various ways. Below the various solutions, labelled as A, B and C, if we click on the faders icon, we can set the intensity of the corrections, which is like controlling the overall Dry/Wet of the modules, or, if we aren’t satisfied and we want to use the Repair Assistant’s suggestions as a starting point, we can open the module chains and tweak the single module’s parameters to taste.

Conclusion

RX7 confirms itself as a must have tool of incredible value, for its vast array of modules, precision, clarity and true gems like the possibility to arrange, save and recall entire chains. Absolutely suggested for everyone who is looking for saving, preserving or “only” asking more for their files. Pro Tools users can now enjoy more AudioSuite tools, and engineers working on multichannel files can be enthusiast too. Having a look around, lately the word Ambisonics is popping out more and more, this is the direction I really hope the next RX will take.

Since my latest review of RX (version 6), I must confess I have used the suite almost daily on both musical and sound design jobs, easily rescuing a lot of files, and rarely opening the manual again because of intuitive functions of this software. Now, with the Repair Assistant, these operations will be even quicker.

The new modules and improvements add some shine to the whole tool, especially Music Rebalance, getting even closer to musicians. I think it will be perfected, analyzing and isolating the various parts even better in the future. Separating single instruments from a track wasn’t something I was thinking about very often before seeing this module. I can just guess what will come next. Variable Pitch and Time, let’s say it again, are tools that easily adapt to musical and Sound Design applications, with a really impressive quality.

The Industry Standard Noise Reducer “RX 7”

We will be taking a look at iZotope’s audio repair tool “RX 7” over the course of a few articles.
RX 7 helps get rid of unwanted noise in a recording, fixes distorted/clipping audio, and more at a level which would otherwise seem impossible without using this tool.
It is an incredibly high quality tool and is considered to be an industry standard.

Of course, recording a clean signal in a noise-free location would be ideal for most situations, but sometimes noise ends up making it on the recording and in many cases, you may not be able to rerecord.
You can bring your valuable recordings back to life using RX 7.

In addition, ver 7 comes with the new Music Rebalance feature. You can break a mixed L/R track into parts and balance volume, mute, or even hear them in solo using this revolutionary feature.
We will look at this in detail later, as it is a unique function found in the RX 7.

Opening Files

In this tutorial we will be using the standalone “audio editor” version of RX7.
When you open it, you’ll first see this file window.

You can choose to drag and drop a file or open a file.

We’ve opened the file as shown.
As you can see, we have purposefully chosen a sample that has clipping (digital distortion) in it for this example.
We will be using RX 7 to fix this issue.

Using Repair Assistant

RX 7 comes with various modules displayed on the list to the right, but you may not know whats what on this list if its your first time seeing it.
But no worries, by using the Repair Assistant feature, AI will automatically detect the issues in the audio clip and select/apply various tools to it.

A pop up window will appear after clicking Repair Assistant, so select the appropriate audio type.

Dialogue refers to narration and conversation recordings, while Music refers to instrument, vocal, and other musical recording, and everything else falls into the Other category.
Press the Start Analysis button to begin analysis.

When analysis is complete, you can compare the original to 3 repaired version options.

The strength of the repair effects can be adjusted in this preview mode as well. Lets try clicking on the fader mark below.

A strength preview will be created, and a slider will pop up allowing you to adjust the strength. Move this fader to adjust the strength of the repair effects.

We could go ahead in Render the audio here, but why don’t we look and see what kind of processing is being done here first.
By putting the cursor over A, B, or C, you can look at the module names included in its module chain.

To see in further detail, click the Open as Module Chain button below.

A pop up window will appear where you can see the details of the module chain.
By clicking on the fader marks, you can view/change the settings within an effect module.

Now that we took a look at the settings, lets render this audio.
Click on the Render button to begin rendering the audio.

Once the rending is complete, the effects will be visible on the new waveform, and repair history will be added below to History.

Each module setting is also recorded in History, allowing you to change the audio to any previous version in History.

Last, Save As to complete the audio editing process.
Though in this example we looked at using the Repair Assistant to get a basic fix of our audio, the potential of RX 7 goes above and beyond this. We will be looking at other modules in our following articles which allow you to edit sounds that RX 7 may not be able to intially pick up.

About Music Rebalance

Last but not least, we will take a look at Music Rebalance for this article.
Music Rebalance breaks a mix track into Vocal, Bass, Percussion, and Other and allows you to adjust each part.

Prepare a mix file with these instrument parts in it to utilize Music Rebalance.
Select Music Rebalance from the module list on the right.

A pop up window will appear, and we can make adjustments while playing using the preview button.

• ①Gain：Adjusts the volume of an individual part
• ②Sensitivity：Raising it raises the clarity of analyzed signal from the source, but introduces sounds from other instrument parts. Lowering it creates more separation, but leads to more unnatural editing noise. The key is to find a balance of numerical amounts between other parts to get the best effect.

You can select algorithms for separation from Separation algorithm.

Izotope Rx-7 Music Rebalance

Under Separation algorithm, Channel independent allows you to run the fastest analysis of parts, but the separation quality will be lower. By going to Joint channel, Advanced joint channel, and so forth, the analysis quality increases but will run heavier on your computer.
Using advanced joint channel would be best when Rendering, but you may want to make adjustments when Previewing depending on your computer specs.

Click the Render button to complete setup and begin rendering.
