Mix Bus is a channel strip plugin from Black Salt Audio for mix bus processing. It combines compression, low-end control and tone shaping in one interface, available in VST3, AU and AAX formats.
Mix Bus is built for the stereo bus rather than individual tracks. Black Salt Audio positions it as a single plugin that covers compression, low-end control and tone shaping, so you can avoid stacking several separate processors on your master chain. The plugin runs on Windows and macOS as a 64-bit effect, with VST3, AU and AAX versions included in the listed formats. It is aimed at producers who want a streamlined bus chain for mixing and final loudness.
The compressor is designed to glue a full mix together, and the developer also offers a Punch mode to add energy and impact. Black Salt Audio says the circuit is tuned to keep dynamic control smooth rather than squashed.
A dedicated low-control circuit is included to keep sub frequencies from becoming muddy. The developer describes it as a way to keep kick and bass tight and controlled, which helps the low end stay stable on the master.
The Sculpt section is a tone-shaping area with Beef, Body and Air controls. According to Black Salt Audio, these add analog-style saturation, warmth and top-end sheen to digital mixes.
For final loudness, a single knob is provided to raise output level. The developer states that this aims to keep dynamic punch, clarity and tonal balance intact while pushing a track toward a louder master.
