iZotope’s award-winning RX 6 Audio Editor is the industry standard for audio repair, restoration, and enhancement. It offers a comprehensive suite of tools focused on alleviating common to complex audio issues. Post production professionals, audio engineers, and video editors alike use RX to transform problematic recordings into production-ready audio.
Sep 20, 2018 iZotope releases RX 7 - Makes Audio Repair Easier for Musicians iZotope’s New RX 7 Makes Audio Repair Easier for Musicians - New features powered by machine learning, like Music Rebalance and Repair Assistant, open up creative possibilities in music production. In this article Supervising Sound Editor and Re-recording Mixer David Barber from Juniper Post shares how he used iZotope RX 7 Advanced as a key part of the dialogue editing stage in the audio post-production of “The Killing Of Two Lovers”. Recently, David had the pleasure of joining his friend.
Design Philosophy
- 2 days ago It should be noted that Music Rebalance is not available as an AudioSuite plug-in, unlike many of the other RX 7 tools. To use it in conjunction with Pro Tools, use iZotope RX Connect in the AudioSuite menu. This will capture the audio from Pro Tools and send it directly to RX 7.
- IZotope RX 3 vs. Adobe Audition, Part 2: Noise and Reverb/Echo Reduction In this final round between audio editing champs iZotope RX 3 and Adobe Audition CC, we compare the two audio editors in noise reduction and reverb/echo reduction.
- I got the early upgrade at a low price, so I took the step from Izotope RX 1 to RX 2 Advanced, at the about the same price as it would cost to buy Izotope RX 2 from the start. I really like the adaptive noise reduction, it does really help when the background noise changes, and gets the job done a little quicker.
- This is our 3rd article on iZotope's audio repair tool RX 7. We will be taking a look at the De-hum, De-crackle, De-reverb, and De-clip modules in this tutorial. Try out these modules to bring your precious recordings back to life.
The RX 6 Audio Editor is a visual, selection-based editing environment. Most of its user interface is devoted to the Spectrogram/Waveform display, an integral part of the RX editing workflow. The display enables you to refine and visualize your audio, allowing for better recognition and selection of problem areas.

iZotope must be feeling the heat! RX has some solid competition in the audio repair space coming from the talented coders at Acon Digital. Acon having set the price of their Resoration Suite at $99, may have been responsible for iZotope’s recent promotion of a new version of RX on sale at $99 (regular price $129).
The RX Plug-in Pack has essentially the same feature set as Acon’s Restoration Suite. So these two products are perfect for a direct shootout. But, what would you really learn if I did the shootout? Not much. After all, I’m not recording in your space, with your mic, facing the issues that you face everyday.
So, here’s how to do a shootout on your own…
Fortunately, both products offer free demo versions. The RX Plugin-Pack is fully functional for 10 days. And, The Restoration Suite’s demo adds a short period of silence at irregular intervals. Keep this in mind when comparing the results.
Now, here’s the fun part. You know how you go out of your way to make sure there are no interruptions when you record a session? Don’t do that.
Grab some copy, preferably something with a few plosives and some sibilant sounds. If you can’t find anything, try the theme song to Gilligan’s Island.
Before you record, you might want to forget to close the door all the way. Or turn on the dishwasher, or the air conditioner, or the — you get where I am going here.
You want a good read in a sloppy environment. Got it? Good.
Record it a second time, but get right up on your microphone and be a bit too loud — on purpose. This will make sense later.
Wait, you aren’t done recording yet. Go find a small fan, a hair dryer, a blender…
You’re looking for things in your environment that make droning noises when they are used. Set these things up so they can be heard inside your usual recording environment. Have a friend turn each thing on/off one at a time while you do another take.
If it’s trash day in your neighborhood or there is construction going on nearby, open the windows and record another take with those sounds as well.
Each of these interruptions has its own sonic signature. And, since no two recording setups are truly alike (believe me, even two identical professionally built booths in two different geographic locations will sound different), your studio will be unique in which frequencies it handles well and which ones seem to pass right through and wind up on the recording.

Now, save WAV files of these recordings being sure to name them so you know what they are:
- gilligan-dishwasher.wav
- gilligan-hairdryer.wav
- gilligan-garbage-pickup.wav
- gilligan-really-loud.wav
You get the idea…
Now, install both demos into the audio editor of your choice. No, really, right now, install them, I’ll wait…
Stop. This is the first test. And, it has nothing to do with the audio you recorded.
- How did the installation go?
- Was it easy?
- Was it straight forward?
- Was the documentation easy to find?
- Was it easy to understand?
Don’t skip this step. It’s more important than you think. If you’re having issues later on, this test is usually a pretty good indicator of how helpful the parent company will be when solving your issue.
Now, open each of the components in your audio editor of choice. Yes, right now, seriously, you know the drill…
- Did all of the components open without issue?
Some plugins expect certain features to be present, but some audio editors don’t implement all of these expected functions. If the components don’t work, it is more likely the fault of your chosen audio editor than the plugin. But, that’s another issue.
Now it’s time to get down to business. Open two copies of a single sound and play with one de-clicker, de-noiser, de-hummer, and de-clipper where you think they are needed.
Before you compare the results, I have a question for you.
- How easy was each component to use?
- Did you immediately understand everything or did it take a bit of poking around before the settings made sense?
Again, a well designed tool is usually a well supported tool. Assess both the interface and your experience using the tool.
Now, sit back and compare the results. And, get a friend to listen to the files as well and give you their opinion too. The more feedback, the better.

Wait, you aren’t done yet. Think of a simple question to ask both iZotope and Acon Digital. And, pose those questions via twitter. Links to their accounts are below:
By now, you know why I’m suggesting that you do this. A responsive company is usually a company that stands behind its products.
