Make Space.

The new Unmask Module discovers and fixes masking issues for you, enabling you to reach new levels of clarity. Make space between two competing tracks, balancing your bass and kick or allowing vocals to shine over your mix.


Distort Responsibly. Or Not.

A slice of iZotope fan favorite, Trash, is now in Neutron 4. Distort and destroy sound with Trash Mode and dial in specific extremes with the Tone Slider and Tame button. Explore the boundaries of weird and wild.


Punch it up.

Make an impact using the new Punch Mode to control and visualize how hard your sounds hit. Add more thump, punch or snap to breathe life into vocals, percussion, bass, and more.

Included with your Purchase of Neutron 4

NEW! Introducing Audiolens

Pair Audiolens with Neutron 4 to match sounds as you mix.

Audiolens will automatically populate saved reference targets to your Neutron 4 Target Library where they will be analyzed by Neutron’s Assistant. You can then quickly match characteristics within the mix of your own track, whether that’s adding some thump to your bass, crisping up your snare, or making hi-hats sizzle. 

Only included with Neutron 4 full version, not Neutron 4 Elements

What people are saying

"Neutron 4 is one of the best new plugins I’ve used in a while!! Completely blown away. Especially by the exciter upgrades."

—Martin Nessi

GRAMMY-winning producer: Ricky Martin

"Transient design, compression, EQ, and harmonic distortion, all wrapped up in one ridiculous sounding package. iZotope, you have done it again."
