In this video, I’m going to cover how to use the brand new Dialogue Isolate module in RX 6 in a post-production context, using a sample that features dialogue.![Izotope rx manual Izotope rx manual](/uploads/1/2/6/0/126008269/768681270.jpg)

After submitting your Challenge Code, you will receive a unique authorization file named “iZotopeRX5AudioEditorxxxxx.izotopelicense.” Copy this file to your offline. Adaptive phase rotation is best used on vocal material, as it can occasionally yield pitch artifacts on musical material. Rotation (deg): Rotates the channel’s phase by the specified degree. When a waveform’s phase is rotated, every frequency is rotated equally. Izotope rx 2 free download. Multimedia tools downloads - iZotope RX by iZotope, Inc. And many more programs are available for instant and free download.
Once you’ve downloaded the test file called, “Post Production_Dialogue Isolate,” for this tutorial from the RX web page, and opened it in RX 6 by clicking and dragging it into the RX application window, or by opening RX 6 and pressing Command+O or Control+O on a PC to locate and open the sample, your RX window should look like mine, with the file, “Post Production_Dialogue Isolate” in a tab on the top-left hand side of the screen.
Informed by machine learning to recognize and separate spoken dialogue from non-stationary background noise, such as crowds, traffic, footsteps, weather, or other noise with highly variable characteristics, Dialogue Isolate can be particularly effective at increasing the level of dialogue in challenging, low signal-to-noise ratio conditions.
Have a listen to this sample, which features some dialogue, and a very noisy background.
[voice sample]
Let’s use Dialogue Isolate to bring the dialogue center stage, and attenuate some of that background noise.
First, we see some parameters in the module. Dialogue gain controls the gain of the components in your audio recognized as speech. We can leave this slider at 0dB to reduce noise, or lower the slider to reduce the level of spoken dialogue.
In this case, we want to reduce noise, and bring the dialogue center stage, so we’ll leave it at 0dB.
Noise gain controls the gain of the components in your audio recognized as noise. We can keep the slider low to increase dialogue intelligibility, or increase it to 0dB while turning down dialogue gain to only hear the isolated noise.
Given the nature of our example, I’d like to really bring down the noise gain so that we can focus on the dialogue as much as possible.
Next, we have separation strength. For large values, meaning if I slide it to the right, the processing will more strictly define what it classifies as dialogue, which can result in more background noise reduction at the cost of possible reduction of speech.
For small values, if I slide it to the left, the processing will more broadly define what it classifies as dialogue, which will allow more background noise through, but will reduce the possibility of speech loss as a result of the processing.
Again, dialogue is king in this example, so I’ll bring my separation strength to 10. I should note that Dialogue Isolate will still process, even when the reduction strength is set to zero.
Let’s press process and listen back to our results.
I’ll press space bar to play our newly dialogue isolated track.

Here’s before.

And here’s after.

Now, I’m still hearing a few clicks in the background, so I’m going to run Dialogue Isolate once more with the same settings to really get the best possible results, given this noisy sample.
Let’s hear the results.

So here’s the initial state before we did any processing with Dialogue Isolate.

In this video, Mr “RX It” otherwise known as Mike Thornton takes a detailed tour around the key new features in iZotope’s RX4 and RX4 Advanced released yesterday. Firstly what’s new in RX4…
Dialogue Denoiser
In RX3, Dialog Denoiser was an Advanced only feature. In RX4, iZotope have made it available so everyone can use this amazing plug-in. The automatic feature is really good so that you can just leave it on a dialog track and it will clean up everything you throw at it, in real time, with zero latency.
RX Monitor Plug-in
This is a plug-in that you can use in Pro Tools so you can monitor what you do in the RX4 standalone application without leaving Pro Tools. This is especially useful for Pro Tools HDX users where using the host computer’s audio output for RX and then your Avid hardware for Pro Tools.
RX Connect Connect Plug-in
![Advanced Advanced](/uploads/1/2/6/0/126008269/364134589.jpg)
As well as the RX Monitor plug-in, iZotope have added RX Connect, making it easy to export audio out of your Pro Tools, so you can use all the features that are in the standalone version of RX4 before sending the processed versions back to your Pro Tools session.
Adaptive Hum Removal
Now with the Hum module in RX4, you can notch out fundamental hum frequencies that change over time, like an analog recording where the speed may drift.
Clip Gain
We have had clip gain in Pro Tools for a while now, but adjusting the levels within RX hasn’t been so easy. Not anymore, with this non-destructive feature now if there is a louder section you can pull it down, or if the contributor drops their voice then you can bring the level up.
Reverse Your Audio
Now you can also reverse the audio in RX4. It only works on rectangular selections but that does mean you can reverse the low end and leave the high frequencies unprocessed which has great sound design possibilities.
What’s New In RX4 Advanced?
EQ Match
With EQ Match you quickly learn the EQ of a source audio clip and easily apply that EQ curve to a target audio clip. It is great for handling audio from the same contributor via different mics in different locations.
Ambience Match
With this module you match the atmos of two different audio recordings with ease. You can take the ambient noise from a source audio clip and apply it to another audio clip, or create long sections of constant ambient noise to insert under inconsistent dialogue recordings.
Leveler
With Clip Gain in RX4 you can manually balance out vocals, dialogue, and voiceovers. But with the Leveler module in RX4 Advanced you can take a whole clip and even out the levels automatically, giving you consistent tracks very quickly. This is really useful especially on documentaries. Here is a take where the contributor gets louder at the end.
Loudness Compliance
With the move to loudness normalization we need to be able to quickly measure and adjust clips so they comply to the appropriate loudness delivery specs. The Loudness module will process whole program mixes or segments to comply with international industry standards.
Other Features
That’s a quick look at the key new features in RX4, there are a load of little improvements throughout the application including a new look and a new Export and Save As options, which I am already finding very helpful.
IBC 2014 Supermeet
I am at IBC 2014 this weekend and I will be demonstrating some of the new features of RX4 and RX4 Advanced at the Creative Pro User Group Network Amsterdam Supermeet at the Hotel Krasnapolsky on Sunday 14th September at 7pm. Do join me if you can.
Groove 3 RX4 Explained
Izotope Rx Manual
I am hard at work producing a new Groove 3 title - RX4 Explained. It will be even longer than RX3 Explained which ran out at 32 videos with a total duration of 4.5 hours. RX4 Explained which will cover Rx4 and RX4 Advanced will be at least 5 hours and come to some 38 videos. It is expected that RX4 Explained will go on sales at the beginning of October.
