Designed to introduce users to the powerful possibilities of editing audio within the RX platform, iZotope’s RX Elements Version 7 comprises four of the real-time modules inside of RX 7 alongside their standalone audio editor.This provides the ability to use the spectrograph to visualize audio, whereupon you can use the four tools provided to process specific segments of the audio spectrum. Nov 29, 2018 RX 7 Advanced has every RX feature and is where most of the post-production-related tools are found. Below that is RX Standard, which has just about all the tools that could be used for audio repair in music production. At the bottom is RX Elements, which has a much lower price but a much more stripped-down toolset.

Repair Assistant
The game-changing Repair Assistant is an intelligent helper that can detect noise, clipping, clicks, hum and more—meaning you can now solve common audio issues faster than ever, like clipped guitar or nasty hums. Use Repair Assistant in one of its three modes to identify and remove problem areas. Choose from four suggestions, giving you the options you need, no matter the project.
Music Rebalance
Also new in RX 7 is Music Rebalance, a powerful source separation tool that allows you to enhance or isolate elements of an audio track. Drums too loud? Vocals not loud enough? Are other instruments too present or is percussion not punchy enough? Easily re-animate a mix using its four sliders. You can also create instrumental versions of songs by removing the vocal elements, or isolate the vocal to prepare a remix.
Variable time and Pitch
You can now alter pitch without affecting the timing of your audio and conversely, alter the time without affecting pitch with the new Variable Time and Variable Pitch modules.
Dialogue Contour
With the new Dialogue Contour module, easily improve the performance of a line or even create a new performance by altering the pitch contour of the dialogue to adjust the intonation of the speaker. Select a region of audio you wish to alter, and then click and drag to adjust the contour curve.
Dialogue De-Reverb
The brand new Dialogue De-Reverb module is powered by machine learning to reduce the presence of reverberations around dialogue.
Multichannel
RX 7 Now supports multichannel which means you can quickly and easily edit one, multiple, or all channels of audio (up to Dolby Atmos 7.1.2) using any of your favorite repair modules.
Available As Audiosuite Plug-ins
With RX 7, we have introduced faster and easier workflows with new Audiosuite Plug-in versions of beloved modules like Dialogue Isolate, De-rustle, Breath Control and the new Music Rebalance.
Refreshed UI
And lastly, fans of RX will notice the new look of version 7....module icons are brighter, more refined and look consistent with the rest of the iZotope plugin family, making it easier to find the tools you need, faster than ever.
As you can see, it’s no surprise that RX is the Emmy award-winning repair suite trusted by top music and post production engineers, and with RX7 you get access to a whole new set of groundbreaking tools to effortlessly tackle any audio problem. Learn more today.

Tutorial on Commonly Used Modules
This is our 3rd article on iZotope’s audio repair tool RX 7.
We will continue to look at editing using different modules.
Though many modules are included, I have chosen a few which I find personally useful and common to take a look at.

De-hum
First take a listen to this sample.
https://sleepfreaks-dtm.com/wordpress/wp-content/uploads/2020/03/Hum_Crackle_pre.mp3
https://sleepfreaks-dtm.com/wordpress/wp-content/uploads/2020/03/Hum_Crackle_pre.mp3
We can hear a low humming noise as well as a constant crackling sound as well.
Lets try to get rid of these.
Lets try to get rid of these.
We will be using De-hum to remove the hum noise.
Hum noise is usually based around low frequencies in the 50-60Hz range, and is a noise that contains a number of harmonics.
We could select 50 or 60Hz from Base Frequency, but if you want AI to make the choice for you, click the Suggest button at the top.
We could select 50 or 60Hz from Base Frequency, but if you want AI to make the choice for you, click the Suggest button at the top.
This will analyse the sample and Free mode will allow it to set a more accurate frequency.
The hum noise can been reduced greatly but if the voice has been negatively effected as well, we can lower the number of harmonics down right on the brink of effecting the main sound. We can do this from the Number of harmonics fader.
Next lets adjust the amount of cut. You can make changes from the screen, but the frequency points can get shifted in free mode so we’ll enter numerical changes below.
Find a point where the noise isn’t noticeable yet the vocal remains clean.
For the low end, you can cut up until the point where it starts effecting the vocal. We will turn the High-Pass Filter on and cut under 100Hz.
Though you most likely won’t be using the Low-pass-filter, it may be necessary depending on the type of noise present.
If we want to make more detailed edits on the harmonics we can choose a different Linking Type.
For the default ALL setting, moving the slider here will have a slope effect on all frequencies.
By selecting Odd/even you can control the odd and even harmonics separately.
The Slope slider will help lower the reduction effect on higher frequencies.
When None is selected the link is removed, allowing you to control the Gain of individual harmonics.

De-Crackle
Next lets look at getting rid of the crackling pop-like noises.
We will be using De-crackle.
We will be using De-crackle.
- Quality:Low will work faster, while High will provide a better sound quality. Medium may yield better results than High depending on the situation, so its best to listen and compare this settings.
- Strength:Determines the strength of the effect, and a higher setting will get rid of more noise but can negatively effect the vocal sounds. Use “Output crackle only” to hear just the crackle sounds and find the right setting.
- Amplitude skew:Allows you to determine the amount of noise editing by the volume of the input signal. Turning it to the right focuses on the louder areas, while turning it to the left will do the opposite. We can set this higher if dealing with clipping noise, but for small detailed crackling noises such as this, it is best to set this parameter on the lower side.
For noise that couldn’t be completely removed, we can try using Spectral De-noise which we took a look at in our previous article.

https://sleepfreaks-dtm.com/wordpress/wp-content/uploads/2020/04/Hum_Crackle_processed.mp3
As you can hear, we have been able to clean up the audio.
De-reverb
Now lets change the sample audio and take a look at the unique De-reverb.
As the name implies, this helps remove reverb and room reflections in a recording.
First lets hear the sample for this example.

We can clearly hear the reverb in this sample.
We will be using De-reverb on this audio.

Though all of these parameters may seem confusing, we can utilise RX 7’s special feature here and get some automatic settings using the Learn button.
To dive a little deeper into the editing, we can leave the Reverb Profile frequency settings set by Learn as is, and adjust the Reduction and Tail length to yield big results.
- Reduction: Increases the amount of reduction of reverb. We want to raise this higher but it will cut out vocal frequencies if set too high, so its best to adjust it to find the right balance.
- Tail length:The further right its pulled the more it works on longer reverb tails. If you get unnatural changes in the vocal sound, be sure to pull this back a little to the left.
- Artifact smoothing:Adjusts the frequency detail of noise removal. Setting it low results in some artefacts in sound, but will increase the amount of reverb reduction. If set higher, you will have less artefacts and a smoother sound, but more reverb will be left over. Its best to listen and find a balance in the middle.
- Enhance dry signal:Increases the volume of non-reverb sounds and expands the dynamic range. This works great on dialogue and human vocals.
The resulting audio after adjusting each parameter is as follows:

https://sleepfreaks-dtm.com/wordpress/wp-content/uploads/2020/04/Reverb_processed-1.mp3
Though its not a completely dry signal, a considerable amount of reverb has been edited out.
De-clip
Next, if we happen to accidentally distort audio during recording we can use De-clip to remove clipping noise.
We have a sample prepared for this as well.
* Be aware that this sample is louder than the previous examples.
https://sleepfreaks-dtm.com/wordpress/wp-content/uploads/2020/04/Clip_pre.mp3
* Be aware that this sample is louder than the previous examples.
https://sleepfreaks-dtm.com/wordpress/wp-content/uploads/2020/04/Clip_pre.mp3
In de-clip we will first setup the threshold of clip sounds. We will use this histogram as a reference but it looks like nothing is displayed at the moment. The histogram will be updated depending on the selected area, so lets first select the portion with vocal audio contained.
If you still don’t see anything, zoom out in the Histogram. Because the majority of sound is clipping, we can see quite alot reflected in the higher volume areas.
Izotope Rx 7 Elements Clipping Free
By pressing the Suggest button, it will automatically set the Threshold to the suggested point.
Its clipping to the point that that nothing is visible in the center, so it’s set to 0dB. If the audio isn’t this distorted, we would set the threshold a little below the clip.
The remaining parameters work as follows:
- Quality:If your CPU can handle it we suggest using High. If your computer can’t handle the strain when using this as a plugin, use Medium or Low.
- Makeup gain:Most distorted recordings are too loud to begin with, so we will be lowering this. You could adjust this parameter so that the fixed audio matches the volume of your other takes as well.
- Post limiter:Applies a peak limiter at the end to prevent the edited audio from going over 0dBFS. Its best to tick this box.
Lets hear how the sample sounds after making adjustments.

The sound is much cleaner and its hard to believe it was distorted.
