RX is the well-known industry standard for repairing damaged audio. RX3 was released last fall as a paid upgrade to its popular predecessor. It refined some tools, and introduced some new ones, notably the Dereverb and realtime Dialogue Denoise modules.

And, since I record and master field recordings, this post will have a strong sound effects mastering slant. New to RX? No problem. You can access these modules in the stand-alone RX app. RX also offers plug-ins that will work with your editing software. The native app I find offers more control, once you get used to it. Most of what I explain today will deal with that app. Now, RX is a complex tool. It has many features. You may not touch some functions for years. Results depend on the skill and ear of the mastering technician.

They also depend on the audio being repaired, say, between sound effects and dialogue. The design has changed considerably. RX3 retains the dark interface, but is more modern. Modules and the edit window are cleaner, organized better, and generally easier on the eyes.

RX3 Bypass Button. You can now open multiple files at once. RX2 could only open one file at a time. RX3 allows you to open RX3 Tabs. RX2 Batch Button. RX3 adds a new playhead to the edit window. Dragging the playhead acts as a scrubbing tool. I find the software is snappier, and smoother. When denoising, RX2 usually requires about 1. The result? RX2 took 49 seconds. The same file processed in RX3 completed in 9 seconds.

What changed in the upgrade to RX3 from RX2? There are many subtle changes. This module quickly and effortlessly repairs clipped audio. RX3 adds a cool stereo historgram. RX2 previously displayed the waveform level in a single, merged bar. RX3 separates them so you can see clips divided into left and right channels.

The largest change is the availability of click types within the Declick tab. You can now choose between a Click, Thump, or Discontinuity. This module has the most significant changes from the RX2 version. It has been vastly simplified.

Previously, the RX2 denoise module offered two tabs: simple and advanced. Still with me? In fact, I think that the tools there are absolutely essential to achieving any decent sound effects denoising results. So, I was surprised to notice that some of those tools no longer work the same way in RX3 basic.

RX2 Smoothing Controls. According the rep:. Again, dialogue crew, vinyl enthusiasts, and film restoration techs may have different results. RX2 Denoise Auto-Learn. That was a helpful tool that automatically scanned selected audio for the best, cleanest noise profile. Gain now adds a Normalize function , which was sorely lacking in RX2 basic. However, RX3 removed the Scan button. I found that option helpful when adjusting gain. That displays info by merely highlighting a region.

It automatically updates when new areas are selected. Notice the yellow playhead in the image below. Clicking that makes the cursor jump to the point referenced. What does RX3 basic add to the previous RX2 offerings? Well, three modules from RX2 Advanced have been demoted. Not all are supported, and you can only open one plug-in at a time.

However, this feature makes RX considerably more useful. Add Waves EQ or compression. Insert free VST metering software. A substantial feature. Dithering is used to tame the quantization distortion that happens when converting between bit depths due to requantization.

Dither also preserves more of the dynamic range of a signal when converting to a lower bit depth. It also adds some additional fine-tuning options to existing modules.

It also offered some additional Denoising options which some people swear by. The story is a bit different with RX3 Advanced.

It also improved some existing modules. The advanced version of Declip allows you to unlink the ganged stereo declip controls. This allows you to declip each channel at a separate level. Channel Operations. One interesting option: you can now extract or remove the center of a stereo file. These were also available in RX2 Advanced. Most noise profiles will be static.

What do you do if the noise swells or ebbs? I use it for some tasks. Those are aimed towards dialogue tasks, though. However, RX, with its multiple tools, powerful algorithms, and ease of use outshines most competitors. The value for the software, however, is strong. RX3 offers increased speed under a new coat of paint. Dozens of smaller features contribute to a more intuitive workflow. Depending on your projects, these features, along with the the three new Plug-In Hosting, Dither, and Resample modules, may or may not be enough to upgrade.

RX3 Advanced is a different story. The Dialogue Denoiser, Dereverb, and additional Denoising options will have a significant impact on the quality of your restoration work. Even the basic RX version will save your audio. It is powerful software, works well, and I absolutely love it. I use RX regularly when mastering my sound effects libraries. The Denoising, Declipping, and Spectral Repair features are extraordinary.

The Declicker is also pretty good. All tools are at least decent, and at the most, exceptional. Every time I use RX, the tools typically recover audio I was certain was destined for the trash bin. It produces jaw-dropping results fairly easily, and only improves with experience. The first will list general ideas and perspectives behind audio restoration. Want to test drive RX3?

iZotope RX2 vs RX3 – What’s Changed?

Restoration software such as Izotope's RX2 can breathe new life into damaged audio — with the right moves from the user! In this article, I'm going to share some power-user hints and tips that will help you get the best from it. For this reason, my number one feature request would be for Izotope to improve the links between DAWs and the stand-alone application, perhaps in the same way as Synchro Arts have done with Revoice Pro. The basic version of RX has five main restoration modules. Remove Hum can eliminate low-frequency noise such as mains hum, along with up to seven harmonics.
