How to use RX Connect in Steinberg Cubase or Nuendo The RX Connect plug-in sends a clip to the RX standalone application for editing and repair. This gives you access to all of RX's modules in one place, and provides the benefits of RX's offline processing and visual interface. To get started, select an audio file from your computer using the “Open File” button, or simply drag and drop it right into RX 7 Standard. Up to 16 audio files can be opened at a time, so feel free to work on many different audio files in parallel.
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. iZotope RX 7 Tutorial ③ – Video AccessPurchase hereDe-hum
First take a listen to this sample.
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.
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. ![]()
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.
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.

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. https://sleepfreaks-dtm.com/wordpress/wp-content/uploads/2020/04/Reverb_pre.mp3
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.
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
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.
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:
Lets hear how the sample sounds after making adjustments.
https://sleepfreaks-dtm.com/wordpress/wp-content/uploads/2020/04/Clip_processed.mp3
The sound is much cleaner and its hard to believe it was distorted.
This completes our look at some commonly used modules in RX 7.

That said, RX 7, the latest version of the toolkit, also boasts various features that make it a powerful asset for commanding and elevating musical performances. Whether you’re working with post production or music production, this feature guide will overview some of the essential components that you’ll want to be aware of to get the most out of RX 7 Standard.
Overview
RX 7 Standard has two primary components: the standalone RX Audio Editor, and a collection of plugins that can be used right within your DAW. We’re going to focus primarily on the standalone editor, which hosts some of the most powerful functionalities RX 7 Standard has to offer (and also includes all of the individual plugins).
When you open up the editor, you’ll be greeted by a blank slate that looks something like this:
To get started, select an audio file from your computer using the “Open File” button, or simply drag and drop it right into RX 7 Standard. Up to 16 audio files can be opened at a time, so feel free to work on many different audio files in parallel. Once an audio file is loaded up, the GUI will display a spectrogram representation of your waveform:
Pro Tip: Want to see a standard waveform rather than a spectrogram display (or a little bit of both)? Use the slider on the bottom left of the GUI to adjust the waveform / spectrogram opacity:
This is the basic setup for using RX 7 Standard – you can now begin editing and enhancing your audio using the modules accessible via the right-hand bar. Though we won’t go through all of them, we’ll highlight some key components – starting with Music Rebalance.
Music Rebalance
One of the biggest new features introduced in RX 7 Standard is Music Rebalance, an intelligent tool that employs a machine learning-trained algorithm to identify voice, bass, percussion and other individual components within a greater mix. With Music Rebalance, a mix can be adjusted and re-animated regardless of whether you have the stems at hand. Subtly boost your bass and percussion, or fearlessly isolate or remove vocals from a track according to your needs.
Once you click on the Music Rebalance feature, it’ll open up a separate window that looks something like this:
Let’s explore some of the adjustable parameters in greater detail:
Pro Tip:Each setting you create can be previewed, bypassed, compared, and rendered. Consider previewing a lower quality demo before comparing, since the latter can take some time to load. That said, the compare function is extremely helpful for experimenting with and A/Bing different sensitivity and gain settings before choosing one to render.
Repair Assistant
Another significant addition brought to RX 7 Standard is Repair Assistant, a feature that detects noise, clicks, sibilance, and more so that you can clean up your audio with more efficiency and effectivity than ever. You can access this intelligent helper by pressing Repair Assistant button on the top right corner of the application. This will initiate a menu that prompts you to identify a material type – dialogue, music, or other:
Once you select the appropriate source and hit “Start analysis,” Repair Assistant will begin analyzing your audio for issues in clipping, clicks, hum, and noise:
Pro Tip: Confident that your audio already sounds great? If Repair Assistant doesn’t find any issues in these categories, it will still generate some subtle cleanup processing chains for you.
After its analysis, Repair Assistant offers you three possible solutions with 10 second previews that can be easily compared and contrasted against the original audio:
Pro Tip: Use the intensity variant buttons (right below each preview spectrogram) to generate two additional intensity variations of a single processing chain:
How To Use Izotope Rx-7 De Noise
De-bleed, de-ess, de-plosive, de-X
One of the first things you may have noticed about RX 7 Standard is how many ‘de-somethings’ occupy the list of modules:
Most of these features address the need to attenuate something undesirable that was captured in a recording, and their parameters are pretty straightforward. Let’s just quickly outline what each module targets:
How To Use Izotope Rx6
Depending on whether you’re doing post production, dialogue editing, music production, or something else altogether, you may find that you use some of these modules more than others. What’s key is learning to identify what issue is present in your signal, and then finding the tool that addresses your particular issue (and for many of the most common problems, Repair Assistant is there to help you out). The above modules are all available as plugins too, which means they can be quickly accessed directly within your DAW.
