HoRNet ZeroBus

What HoRNet ZeroBus is

HoRNet ZeroBus is a stereo mix bus processor that combines automatic EQ balancing with intelligent compression. AutoEQ continually analyzes 31 frequency bands and balances the spectrum in real time, with a control range of 0–200%. Its compressor has two modes: FAT uses parallel 1176-style compression for punch, while GLUE uses serial SSL-style compression for cohesion. The compressor analyzes RMS and peak levels to set threshold and makeup gain automatically. The maker describes using ZeroBus on a mix or master bus, drum bus, or other stereo subgroup. It supports sample rates from 44.1 to 192 kHz, automatically applies 2× oversampling below 88.2 kHz, and has near-zero auto-compensated latency. Listed formats are VST3, AU, and AAX for Windows 10+ and macOS 10.13+. The one-time purchase price is €24.99. A demo is available for Windows and Mac, but its volume turns down every 30 seconds and host automation is unavailable. The product page states a 15-day money-back guarantee and free updates.
