Music Production Suite 4.1 gives you new options for audio repair, creative reverb, unmasking vocals and instruments, and creating outlandish new sounds. Neoverb is the first-ever iZotope plug-in that helps you detect and unmask reverb from other tracks, keeping your mix mud-free while you add your own creative touch.


Neoverb is an intelligent reverb plug-in powered by Exponential Audio algorithms to help you get a great reverb sound for your instruments and vocals in less time. Neoverb offers you three useful reverb engines in one intuitive interface, with Advanced controls that let you customize the reverb’s sound without needing to add additional corrective plug-ins or track routings in your DAW. 

But if you’re just getting started in the world of reverb mixing, you can use an easy, guided Reverb Assistant to set up a great reverb for you. Reverb Assistant adjusts and blends reverbs in real time, then listens and unmasks the reverb from the original signal to prevent buildup in your mix.

New features:

  • Reverb Assistant: Get a great reverb for any track, with an easy four-step Assistant that adjusts iZotope Neoverb’s settings in real time. Create complex, customized reverbs, and spend time in menus and settings.
  • Blend Pad: iZotope Neoverb’s innovative Blend Pad gets you further, faster by helping you visualize and mix three different types of reverbs at once, to create a unique reverb tail that fits your track.
  • AI-powered EQ Section: Get a great reverb sound without using a long plug-in chain, with a fluid EQ section helps you clean your input signal and keeps your reverb tail from overwhelming your mix.

Pro-tip: You can automate the Blend Pad! By using touch automation within your DAW, you can move the Blend Pad node, creating exciting movement in a production—like in a transition from a verse (smaller space) to a chorus (larger, more expansive space).

Nectar 3 Plus

Updated Unmask Module in Nectar 3 Plus

Nectar 3 Plus is a go-to plug-in for creating any type of vocal sound under the sun, whether you’re mixing beautiful pop vocals or extreme metal growls. Nectar 3 Plus introduces an improved Unmask that ensures your vocal will fit in the mix, no matter the style. A new EQ window lets you scale the amount of masking to taste, ensuring your vocal is loud and clear without causing artifacts or loss of energy in your other tracks. The new Dynamic setting tracks the vocal and ensures the unmasking only occurs when the voice is present, keeping other instruments from receiving unwanted EQ cuts.

Unmask features:

  • Unmask EQ: Now you can see your unmasking using a new EQ window that shows you where the cuts are happening. 

  • Amount control: Scale back the amount of unmasking processing applied to keep your processing transparent.

  • Dynamic mode: Engage Dynamic mode, and Unmask only applies EQ when the vocal is present.

Pro tip: Having trouble getting your lead and backing vocals to sit together nicely once reverb has been added to both? Use the masking meter to measure masking occurring between your current Neoverb and other iZotope plug-ins, like other Neoverbs, Neutron 3, Nectar 3, VocalSynth 2, and Relay!
