Everyone knows it's impossible to remove reverb from your audio recordings, right? Wrong. iZotope RX4 is an extremely powerful audio repair suite and includes a very capable de-reverb processor.
In the past, I’ve had numerous instances where I’ve recorded a vocal or voice over in not the most ideal of rooms. Rooms that are maybe a bit too big for the vocalist or that aren’t treated to absorb room reflections and ambiences. I wish I could have had a plugin like RX back then. When I got my hands on RX the first thing I wanted to try was the De-reverb feature, and man was I impressed. Let me walk you through how RX works regarding removing room ambiences to correct those not so ideal recordings.
Your Over-Room Ambience Recording
So for demonstration purposes, I have recorded a vocal in a room that is not the greatest for voice recordings. Here is the vocal recording. It is a medium-big sized room that is open-plan to the adjacent rooms. So it’s not isolated or treated like a proper vocal booth or dedicated voice recording rooms. You can hear the room ambience and even though I’m using a broadcast dynamic microphone, which tries to reject any external voice, it is still not the best recording. Now let’s put RX's De-reverb to the test.
Loading Up De-reverb
First let's take a look at how to use RX as a plugin in your DAW, and then how you can use it as a standalone audio editor, as well as the extra features it has in the mode.
So in your DAW, add the RX De-reverb module as an insert plugin. You’ll see from your plugin list that you can add an instance of the RX module. Choose the De-reverb.
Then you need to learn the reverb type in the audio. To do this, click on the learn button and then play back the audio in your DAW. While playing back, the plugin analyzes the audio and sets up the parameters to what it thinks will remove the reverb from the sound the best.
Listen back—it does quite a good job. Notice how most of the reverb has been removed. That’s quite impressive!

After De-reverb Learn:
Editing the Parameters
Perhaps you want to tweak the results even further? Maybe too many artifacts have been introduced. Then you can dial back the Reduction fader, and even increase the Artifact smoothing dial to reduce this. If you tick the Enhance dry signal, this can also help, but may also introduce more artifacts. So it’s a bit of a balancing act, but I haven’t seen a plugin before that has as good results like this one, nice work RX! Fl studio 12 free download.
You can also tick the ‘Output reverb only', and then hear just the reverb signal in the audio. Plus you can go in and change the amount on the Low, Low-mid, High-mid and Highs. So you have quite a bit of flexibility in altering how the reverb is removed.
In Standalone Mode
Standalone mode, or the Audio Editor mode, is slightly different in how it operates, as well as having some extra features not present in the plugin modules. Open up the standalone version of RX, and then drag the audio into the audio window. This will display the waveform.
Now select the audio waveform—you can use the shortcut Command-A (Mac) or Control-A (PC). Navigate to the De-reverb module on the right panel.
Click the learn button to analyze the audio. You’ll see you don’t need to play back the audio. It’ll do the analysis without the need to playback in real time.
The rest is pretty similar to the plugin. You can edit the reduction amount, and the EQ bands. What is different is that you have different undo/saved states in the bottom right. When you first load your audio track, it’ll have the Initial State, and then each time you analyze the audio, it’ll create a new state. So you can compare by jumping back to the initial state, or make new states and compare the De-reverb settings.
Ambient Match
Another cool thing you can do in the standalone mode is use the Ambient Match feature. So let’s say you’ve gone in and edited out the gaps between the voice in your recording. This tends to break up the continuity of the sound in some cases. So what works well is to insert bits of the room ambience back into the sound. And the Ambient Match feature makes this super easy. Just make a small selection of an area on the audio waveform that contains some room ambience. Then choose the Ambient Match module on the right panel.
Click on the learn button, and the room ambience in the track will be recreated. You can then either click Preview to hear how it sounds. If it’s not quite right, you can fine-tune your selection and learn it again. Then click Process to add this to the audio.
Conclusion
That’s how easy it is to use the De-reverb module in the RX Audio Editor to remove and clean up the reverberated signal in your audio. I found that the plugin had removed quite a bit of the ‘background sound’, but at the same time, you could go in and tweak the parameters if you wanted to reintroduce some of that background noise back in, or edit how it was being removed in the different frequency bands. Plus you can use the Ambient Match feature to pull in room ambience that may have gotten removed when you edited the audio, which always comes in handy when you're doing hard edits on audio such as dialogue. This feature helps in making the audio feel more seamless after the edits. I’d really suggest using an application like RX if you are involved in quite a bit of voice and dialog work. It can help improve your voice recording and even save recordings you didn’t think you could even use.

Ambience Match
The Ambience Match module lets you match the noise floor of one recording to another recording. For example, you can recreate the ambience of a live set on your ADR tracks. The module analyzes the noise floor in your recording and creates a snapshot of it, similar to the noise print in the De-noise module. Then you can use this noise print to synthesize similar noise in another recording.
The Ambience Match algorithm analyzes an audio selection, rejects silence, and then finds the lowest common denominator (the noise that is common across the audio file) and treats that as the ambient profile.
To train Ambience Match, provide it with a selection of raw noise. If there is no single fragment of raw noise, or you want to save time, speech can be used. The algorithm will intelligently discard speech and only leave noisy parts in the noise print.
To match the ambience between selections: Ipad pro with garageband.
- Open the Ambience Match module (Process > Ambience Match, or by clicking Ambience Match in the modules list on the right side of RX).
- Make a selection in a file.
- Click Learn.
- Make another selection.
- Adjust the Trim level as desired. The Trim control adjusts the level of synthesized ambience.
- Select Output Ambience Only if you want the selection replaced with only the ambience from the first selection.
- Click Process.
Note: The Ambience Match module cannot reduce the amount of ambience that already exists in the selection, it can only increase it. To reduce the ambience, use the De-noise module.
To create an Ambience Match preset:
- In Ambience Match, click the gear icon to the right of the preset drop-down menu.
- Select Add Preset.
- Enter the name for the new preset.
- Press Enter.
Using Ambience Match as an AudioSuite Plug-In
In addition to applying Ambience Match inside of the RX Audio Editor, it can also be used as an AudioSuite plug-in inside of Avid’s Pro Tools or Media Composer.

When using Ambience Match inside of Pro Tools or Media Composer, we recommend not learning from audio that contains fades within the selection or the handles. As Ambience Match establishes an ambient profile using the lowest common denominator, learning from audio that’s being faded in may result in inconsistent detection of the noise floor. Handles can be preserved by using Ambience Match in clip-by-clip mode.
Izotope Rx 6 Advanced Manual
When using Pro Tools, you may see an inconsistent result as a result of Pro Tools adding dithering to fades, which varies based on the session's bit depth. Since this dithering noise almost certainly doesn't match the material's noise profile, this will throw off Ambience Match. If you’re running a session in 16 bits, the dither added by a fade will be sufficient enough to affect the detection algorithm. The problem is less pronounced in 24 or 32 bits. To adjust the bit depth of your session, go to Setup > Session in Pro Tools.
