Firespacer

The deal

$27.60 at Loot Audio (down from $69.00). The sale ends October 6, 2026.

What it is

Firespacer is a mixing effect plugin from United Plugins that fixes frequency masking between tracks. It analyzes one track through a sidechain input and removes the overlapping frequencies from another track, so both sit clearly in the mix. It works in real time and is available in VST, VST3, AU and AAX formats.

Who it's for

Producers and mixers who struggle to keep vocals, kick and bass, or layered synths from fighting for the same space. It suits anyone who wants cleaner separation without hand-carving EQ cuts on every track.

Key features

• Release and Precision controls let you tune how the plugin reacts to the sidechain signal
• Internal 64-bit processing supports sample rates up to 192 kHz
• A 15-day unlimited trial and free lifetime updates are included
