Software Review
In the iZotope Catalyst Series, the developers now present a third program, the delay app Cascadia. We check this up a little extra…
After the success of Aurora and Plasma, iZotope continues on the beaten path and presents Cascadia, an intelligent tape-delay app with what the developers call “adaptive unmasking”, a function that automatically ensures that you experience the sound as both clear and focused.
Cascadia is a very versatile delay. For us users, this is a most welcome addition to our other delay apps. We should perhaps also mention that several of the competitors have developed apps with a similar concept; Swedish Softube just launched their Echoes and from German Hofa Plugins we have now seen Color Delay. We hope to return to both of these, but today it is iZotope Cascadia that is placed on the test bench.
Ducking and Adaptive Unmasking
There is an inherent problem with most reverb and delay apps. The problem is that reverb tails and delays have a tendency to mush the sound, if it is placed on top of fairly dense tracks. You want the effect to come into its own between different vocal or instrumental phrases; not lie as a constant blanket over the entire track. In the past, sound engineers could solve this by sending the signal via a side-chain where they used a gate or a compressor to keep the effect under control when the sound was at its most intense. This is called “ducking”, and the result was that the reverb or delay was kept somewhat at bay during the important phrases and then allowed to bloom, when the vocal phrases temporarily fell silent.
Other delays and reverbs have had similar ducking features, but iZotope has refined the whole process and takes this a few steps further. Not only does it adjust the level of the effect, but it also dynamically filters the effect signal, giving you a very useful effect that is always there without taking attention away from the original signal.
Masking
What is called “masking” occurs when two different signal sources are too close to each other in volume and frequency content. Typical phenomena of this kind occur when a pianist is to accompany a solo singer. If neither the instrumentalist nor the sound engineer are experienced enough, it can be a really boring experience – I have heard this countless times on live TV. The pianist is hammering away in the same frequency range as the singer, and perhaps also trying to drown out the vocals. An experienced producer can control the whole thing by partly arranging the piano accompaniment so that it is not exactly in the spectrum where we find the vocals. Of course, you can also demand that the pianist adopt a slightly more restrained playing style, which could leave room for the important vocals.
This problem also tends to rear its ugly head when adding a delay or reverb signal to an original signal. iZotope has previously introduced several plug-ins – Neutron, Nektar and Neoverb – that offer tools to deal with the masking problem. Neutron 5, for example, offers both Dynamic EQ and an Unmask function, but when it comes to the problem of the delay mucking up the input signal, Cascadia may be the perfect solution.
iZotope Cascadia
In Cascadia you don’t have to fiddle with complicated side chains and other things; all settings are accessible directly from within the app. Here you can easily create nicely bouncing delays, tight slapback echoes or other useful effects, without taking the focus off the vocal or instrument that should be in the driver’s seat for a single moment. Muddy mixes are a thing of the past.
The four main advantages of Cascadia are as follows:
- Adaptive Unmasking Dynamically EQs the delay signal to keep the dry signal present.
- Flexible Delays You can choose to sync the delay to your DAW, set a custom delay, use ping-pong effects, play the effect backwards, or give it a bit of a vintage pitch shift.
- Intuitive Controls A very efficient interface with easy-to-understand controls.
- Lots of useful Presets More than 50 professionally designed presets that include both spatial and more textural sounds.
The User Interface
If we start by looking at the interface itself, most of it fits in one and the same window, which of course can be adjusted in size completely according to your wishes. At the top of the window there are buttons for the Reverse function, for “sunning” the Delay, for Bypass, and for selecting a preset.
Along the left edge you will find settings for syncing to DAW programs and in that case which time signature you want to use. There is also a button for selecting pingpong delay (it is illustrated with a table tennis racket plus ball – just such a thing), a large knob for the delay amount, two sliders for Feedback and stereo width, plus two knobs for modulation (depth and rate).
On the right edge of the image we find a slider for the amount of unmasking, plus settings for Attack Release and Sensitivity. There are also two buttons for Bypass and for listening only to the signal that is “masked” away. The rest of the window shows a combined frequency and level image of the signal, and at the bottom you can set the cutoff frequencies of the Hi- and Lopass filters. Everything feels incredibly intuitive. Just keep in mind that Cascadia is primarily designed to be used as an insert effect. If you want it in a tap (send/return), you should press the Solo Delay button and send it a generous signal.
What does it sound like?
Well, it sounds incredibly good. Neat and tidy, without being disturbed by any effects that crowd in. They are just there and lift and amplify the basic sound in a very exquisite way. Nothing in the delay effects crowd in or wants to be in the foreground. And it is incredibly easy to create a balance between the original signal and all possible effects.
As a user, we also have a rich selection of different effects and masterfully programmed presets to choose from.

Summary
iZotope’s Catalyst series contains three powerful effect plugins today. Plasma (saturation), Aurora (reverb) and Cascadia, with different delay effects. Unlike Ozone, Neutron and Nectar, the Catalyst series effects have a significantly simpler and more clear interface. However, this does not mean that they are in any way “simple” as effects. Quite the opposite! They are all three incredibly powerful and capable effects. We hope to be able to come back with tests on the other two in the Catalyst series, today it’s about Cascadia.
With Cascadia you can create delay effects that never get in the way of your most important audio tracks. Thanks to iZotope’s Spectral Unmasking technology, they have the ability to always stay just the right amount in the background. An incredibly intelligent delay effect, in other words.
Whether it’s nice, discreet slapback echoes, large, swelling delay cascades, or just a little bit of reverb, it always sounds clean and nice. No long effect tails are there to interfere with your, or others’, solo efforts. And you also have a lot of really useful preset settings to start from.
Your mixes will sound so much better with Cascadia in place among the effects plug-ins, and the soloists you’ve recorded – whether they’re vocal or instrumental – will be forever grateful that they can now shine in all their glory. Please send the developers at iZotope a thank you note when you receive rave reviews for your mixes in the future! I certainly will.
