HoRNet ZeroBus
What it is
HoRNet ZeroBus is a stereo mix-bus processor that combines automatic EQ balancing with intelligent compression. AutoEQ continuously analyzes 31 bands and balances the spectrum in real time across a 0–200% control range. FAT provides 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 ZeroBus for mix or master buses, drum buses, and other stereo subgroups. It supports 44.1–192 kHz audio, automatic 2× oversampling below 88.2 kHz, and near-zero auto-compensated latency. Listed formats are VST3, AU, and AAX on Windows 10+ and macOS 10.13+. The one-time price is €24.99. A Windows and Mac demo is available, with volume turning down every 30 seconds and host automation unavailable. The product page states a 15-day money-back guarantee and free updates.
