In classic analog mixing consoles like Neve or SSL, each fader includes a channel strip. This is a series of in-line processors that can be applied to each individual input and usually consists of some combination of an EQ, gate, and compressor. If a studio mixing engineer doesn’t use the built-in effects, then they may have a rack of outboard effects units that can be patched in and out of the mixing console. iZotope offers a number of processing products that are the software equivalent of the channel strip or effects rack.
I’ve written about iZotope products in the past, so I decided to take a look at their Mix & Master Bundle Plus, with is a collection of three of their top products – Neutron 3, Nectar 3, and Ozone 9. These products, along with RX, are typically what would be of interest to most video editors or audio post mixers. RX 8 is a bundle of repair effects, such as noise reduction, click repair, and so on.
Depending on the product, it may be available within a single plug-in effect, or several plug-ins, or both a plug-in and a standalone application. For instance, RX8 and Ozone 9 can be used within a DAW or an NLE, in addition to being a separate application. Most of the comprehensive iZotope products are available in three versions – Elements (a “lite” version), Standard, and Advanced. As the name implies, you get more features with the Advanced version; however, nearly everything an editor would want can be handled in the Standard product or for some, in an Elements version.
Each of these products is an AU, VST, and/or AAX plug-in compatible with most DAWs and NLEs. It shows up as a single plug-in effect, which in iZotope’s parlance is the mothership for processing modules. Each product features its own variety of processing modules, such as EQ or compression. These modules can be stacked and arranged in any order within the mothership plug-in. Instead of having three individual effects applied to a track, you would only have one iZotope plug-in, which in turn contains the processing modules that you’d like to use. While each product might offer a similar module, like EQ, these modules do not function in exactly the same way from one product to the next. The range of control or type of function will differ. For example, only Ozone 9 includes mid/side EQ. In addition to new features, this newest series of iZotope updates includes faster processing with real-time performance and some machine learning functions.
If you can only buy one of these products and they perform somewhat similar tasks, how do you know what to use? First, there’s nothing to prevent you from applying Ozone, Nectar, or Neutron interchangeably to any individual track or a master bus. Or to a voice-over or a music mix. From the standpoint of a video editor using these plug-ins for the audio mix of my videos, I would simplify it down this way. Nectar 3 is designed for vocal processing. Neutron 3 is designed for music. Ozone 9 is designed for mastering. If I own all three, then in a simple mix of a dialogue track against music, I would apply Nectar 3 to the dialogue track, Neutron 3 to the music track, and Ozone 9 to the master bus.
Working with iZotope’s processing
Neutron, Nectar, and Ozone each include a wealth of presets that configure a series of modules depending on the style you want – from subtle to aggressive. You can add or remove modules or rearrange their order in the chain by dragging a module left or right within the plug-in’s interface. Or start from a blank shell and build an effects chain from the module selection available within that iZotope product. Neutron offers six basic modules, Nectar nine, and Ozone eleven. Many audiophiles love vintage processing to warm up the sound. In spite of iZotope’s sleek, modern approach, you’re covered here, too. Ozone 9 includes several dedicated vintage modules for tape saturation, limiting, EQ, and compression.
All three standard versions of these products include an Assistant function. If you opt to use the Assistant, then play your track and Nectar, Neutron, or Ozone will automatically calculate and apply the modules and settings needed, based on the parameters that you choose and the detected audio from the mix or track. You can then decide to accept or reject the recommendation. If you accept, then use that as a starting point and make adjustments to the settings or add/delete modules to customize the mix.
Neutron 3 Advanced includes Mix Assistant, an automated mix that uses machine learning. Let’s say you have a song mix with stems for vocals, bass, drums, guitars, and synths. Apply the Relay effect to each track and then iZotope’s Visual Mixer to the master bus. With the Standard version, you can use the Visual Mixer to control the levels, panning, and stereo width for each track from a single interface. The Relay plug-ins control those settings on each track based on what you’ve done using the Visual Mixer controls. If you have Neutron 3 Advanced, then this is augmented by Mix Assistant. Play the song through and let Mix Assistant set a relative balance based on your designated focus tracks. In other words, you can tell the algorithm whether vocals or guitars should be the focus and thereby dominant in the mix.
Note that iZotope regularly updates versions with new features, which may or may not be needed in your particular workflow. As an example, RX8 was just released with new features over RX7. But if you owned an earlier version, then it might still do everything you need. While new features are always welcome, don’t feel any pressure that you have to update. Just rest assured that iZotope is continually taking customer feedback and developing its products.
Be sure to check out iZotope’s wealth of tutorials and learning materials, including their “Are you listening?” YouTube series. Even if you don’t use any iZotope products, Grammy-nominated mastering engineer Jonathan Wyner offers plenty of great tips for getting the best out of your mixes.
