Nov 22, 2019 As the industry leader in audio repair, RX 7 introduces Repair Assistant and Music Rebalance, plus tools for any audio post production job. Tune a vocal in a multi-mic’d live recording. I first discovered this trick during one of my own. RX’s Music Rebalance intelligently identifies vocals, bass, percussion, and other instruments in a mix and allows for independent gain adjustment of each. Along with the mixing capabilities of Music Rebalance, RX 8 introduces automatic.

The IZotope RX8 Music Rebalance software is IZotope’s latest offering. They have been the world leaders in audio treatment software for a number of years and make products which are used by production houses, music, T.V and film producers. Tools for removing background hiss, mastering and retuning are all in their repertoire of packages which are refined and updated on a regular bases.

RX8

RX8 is the newest in their line of audio treatment software and we’re gonna be focusing on the ‘Music Rebalance’ feature which separates the audio into individual stem parts and makes it perfect for remixing when you don’t have access to the original stems.

It’s important to remember that this is intended as a software option for the studio and isn’t really meant for live performance. It’s also worth mentioning that there is other software available to DJs for stem separation when performing live. DJ pro and virtual dj both have apps which have a stem separation mode and we’ll be taking a look at both of those soon.

Price

The IZotope RX8 Music Rebalance software on its own is around £280 or just over $300 but there is another option if you just want to try it out for a few months or you want to buy it but don’t have the cash right now.

Rent To Buy

Splice run a rent to buy service on a number of different software packages so you can pick this up for around £15 a month and then as soon as the software is paid off you own it.

Daw Integration

At present isotope are offering integration on all the major DAWs but my experience of using RX8 with Ableton was disappointing. All of the editing has to be done in RX8 so the re-routing of the audio sampler inside Ableton seems a bit pointless. It just seems easier to use both software independently and export from RX8 and then import into Ableton. I’m sure this is something that they will work on for future versions. (If you have had a different experience integrating RX8 with Logic Audio or Pro Tools or any other DAW for that matter then please let us know.)

Stem Seperation

Before we jump into IZotope RX8 Music Rebalance, its probably a good idea to get some context on separating audio into stems. Currently, its very much a work in progress and as each year passes the technology seems to be getting better and better. Therefore its worth bearing in mind that although this software is pretty impressive, its still not perfect and some of the results will be a bit hit n miss. Whether we’re able to get to a place where we can separate individual elements of a track perfectly, time will tell, but things are moving along nicely.

Step-By-Step guide for using ‘Music Bebalance’

Fire-up RX8 and drag the track you want to separate into the main window. Then head over to the music rebalance option at the bottom right hand side of the main window.

Once selected, the feature will show a table with the four main elements of the main audio stem and sliders below them. Vocal, Bass, Percussion and Other will be your four options for separation.

Click on the main wave file to select the part you would like to audition from. Then click preview to play. This will play back the audio depending on the parameter settings of your four track elements. Experiment with different combinations of instrument to see which offer the best results.

Its also worth playing around with the quality and separation settings bellow the rebalance table to see what works best. This will have a big impact on your CPU as RX8 is quite a processor heavy pice of software.

Once you are ready to bounce down your stems you can render individual parts or press separate to isolate and bounce all four parts onto your desktop.

Verdict

RX7 7 was a big step forward in stem separation and while RX8 seems to show improvements with the audio quality and accuracy particularly in the vocal and bass parts, there are still noticeable issues with some of the stems.

However, the exciting part about IZotope RX8 Music Rebalance is that it is starting to produce audio stems that are useable on studio projects. This is particularly exciting if you are a remixer or DJ who doesn’t have access to the individual stems they need.

RX7 is capable of some amazing tricks, and isolating, separating and remixing audio sources is one of its most impressive. Joe Albano shows you how it's done.

The latest version of iZotope’s premier audio repair application, RX7, introduced a number of new modules offering useful and often cutting-edge processing options—the new Music Rebalance module is a good example of the latter. Music Rebalance is capable of isolating three audio stems in a full mix—drums/percussion, bass, and vocal—leaving everything else in the mix as a fourth stem.

Audio separation has been around for a while now, but it remains a work in progress. It’s still not possible to completely separate all the tracks or stems in a finished stereo mix file, and tracks and stems that are extracted are often accompanied by noticeable audio artifacts—a telltale “watery” sound consisting of bits of the surrounding audio that couldn’t be fully isolated from the desired signal. The flip side of extracting individual tracks or stems is the ability to remove a particular part from a finished stereo mix, and this is also sometimes possible, but again, often with a certain amount of artifact, in the form of a ghostly trace of the removed part.
iZotope’s Music Rebalance module can do a surprisingly good job of both extracting and removing parts at times, keeping in mind that—with all implementations of this technology—success is heavily dependent on the particular stereo mix audio file.

But what Music Rebalance consistently does extremely well—with clean, fully natural-sounding results—is allow the user to remix the available stems, which is in fact is its intended purpose.
Here’s an example—a mix where the drums are a bit too loud and the vocal is slightly buried at times, and a little rebalancing is needed—a typical scenario for mastering engineers.
Izotope

If a mastering engineer came across this file and wanted to try to fix these imbalances, he traditionally might turn to tricks like M-S processing, which can provide some degree of isolation between the center and sides of a stereo mix. But in this situation, both the drums and vocal are centered in the mix, so an M-S solution isn’t really in the cards.
But RX7‘s Music Rebalance module is perfectly suited to the task. It’s very simple to operate—the sliders adjust the level of each stem, all the way down to 0 for removal. The Sensitivity controls let you dial up a tradeoff between the isolation of a particular stem and the amount of artifact that may be heard; they really only need to be used for more aggressive level changes—for subtle level adjustments the default setting (5) usually seems to work best.
