Automatic Mixing for Live Microphones

An automatic gain-sharing mixer for macOS. ATOMIX listens to every open microphone and balances them for you, continuously, in real time — so nobody has to ride faders during Live vocals and choirs

How It Works

Instead of you manually bringing up whoever's talking and pulling down everyone else, ATOMIX listens to all your channels continuously and does that balancing automatically. At any moment, channels that are currently active are heard clearly, while quiet or inactive channels ease back — smoothly, automatically, and without ever fully cutting anyone off.

Automatic Gain-Sharing Logic

ATOMIX continuously monitors all open channels. When a voice becomes active, it dynamically shifts the balance to ensure clarity. If multiple voices speak simultaneously, they share the mix seamlessly. When everyone is silent, the system settles into a unity-gain balance, keeping the overall mix consistent and professional.

Automatic Gain-Sharing

Every unmuted channel participates in real-time balancing, ensuring a natural and musical mix at all times.

Adjustable Ducker Speed

One global control sets how quickly a channel relaxes back down, providing tight and snappy control for any session.

Engineered for precision and real-time performance across all major macOS platforms.

Technical Capabilities

Gender-Aware Trigger Filter

Advanced per-channel decision-making that corrects for unusual vocal frequencies, keeping the automix logic sharp.

Pink Noise Reference

A quiet, constant reference signal that keeps silent mics from picking up room noise when nobody is speaking.

Lead / Backing Vocal Groups

Tag any channel as Lead or Backing and control the entire group from dedicated faders for total session control.

Real AU Plugin Hosting

Five insert slots per channel host real Audio Unit plugins. Copy and save your own named presets independently.

System Requirements

ATOMIX runs on both Apple Silicon and Intel Macs, on macOS 15 or later. Any Core Audio-compatible interface works as input/output — USB and Thunderbolt audio interfaces, Dante/MADI hardware, and virtual devices such as loopback drivers, all work the same way since macOS presents them all as ordinary Core Audio devices.

What audio interfaces work with ATOMIX?

Anything that shows up as a Core Audio device on your Mac — USB and Thunderbolt interfaces, Dante/MADI hardware, and virtual/loopback drivers all work, since macOS treats them identically.

Can I move my license to a different Mac?

Licenses are tied to a Machine ID. If you need to move to a new Mac, email info@bjstudios.be with your original order details and the new Machine ID.

How It Works

Instead of you manually bringing up whoever's talking and pulling down everyone else, ATOMIX listens to all your channels continuously and does that balancing automatically. At any moment, channels that are currently active are heard clearly, while quiet or inactive channels ease back — smoothly, automatically, and without ever fully cutting anyone off.

Continuous Listening

ATOMIX continuously shifts how much of each channel you hear in real time.

Smart Voice Detection

It judges how 'active' a voice is, correcting for unusually deep or bright voices.

Group Level Control

Tag any channel as Lead or Backing and control that whole group's level together.

Master Output Leveling

Keeps the overall mix at a consistent, chosen loudness no matter how many mics are open.
