Mix in the Moment

Neutron’s beloved AI powered audio Assistant is now modernized into the new Assistant View, your intelligent control center that produces fast, personalized results. Powered by machine learning, the Assistant View starts listening as soon as you play audio, producing a reference starting point and taking you to an intelligent control center where you can use the Intent Controls to make big sonic improvements. Dial in punch, distortion and width to taste before jumping into the Detail View to fine tune. This is your Mix Assistant, but even faster and more flexible.

Magically Match References

Match references in real time. Like magic. Dynamically match the tone of your track to a sample or stem using the new Target Library with tone matching technology. Communicate your intent to Neutron by loading stem references into your Target Library to enable the Assistant to match your drums, bass, guitar, vocal or audio track to the sound you are going for. Borrow from presets, or build your own with stems, sounds and acapellas for every situation.

Make Space

Neutron 4 discovers and fixes masking issues for you, enabling you to reach new levels of clarity. The new Unmask Module makes space between two competing tracks, balancing your bass and kick or allowing vocals to shine over your mix. Unmask from a track or bus in your DAW, then adjust levels to reach your optimal balance. It’s simple to set up and fixes muddy mixes in seconds.

Distort Responsibly—or Not

A slice of fan favorite Trash is now in Neutron 4. Distort and destroy sounds with Trash Mode allowing you to discover new extremes by blending between different textures. Curate character changes with the new Tone Slider to explore the boundaries of weird and wild. Distort responsibly with the Tame button to preserve dynamic expression as you destroy.

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. Choose from Punch Mode, Modern Mode or Vintage Mode to easily manipulate microdynamics.

Improved UI Look and feel

Neutron 4 has a new look, designed to jumpstart your mixing process. With new panels featuring Intent Control you can jump right in to make both corrective and creative changes. Toggle between the Assistant View and to the Detail View to customize your workflow.

Sidechain Metering in the Compressor Module

See your sound, scope your sidechain. The perfect sidechain? It’s now within reach. Visualize your dynamics with the new Oscilloscope View in Neutron’s Compressor. Use the Oscilloscope View after setting up your sidechain to see your sound as you dial in your perfect sound. You’ve heard compression. Now see it, too.

Improved Performance

Neutron 4 is compatible with Apple silicon-native chips for faster processing.
