What it is
HoRNet ZeroBus is a stereo mix-bus processor combining automatic equalization with adaptive compression. AutoEQ continuously analyzes 31 frequency bands and balances the spectrum in real time, with a control range from 0% to 200%. Compression has two modes: FAT uses parallel 1176-style processing for punch, while GLUE uses serial SSL-style processing for cohesion. The compressor analyzes RMS and peak levels to set threshold and makeup gain automatically. HoRNet describes ZeroBus for mix or master buses, drum buses, and other stereo subgroups. It supports 44.1–192 kHz, automatic 2× oversampling below 88.2 kHz, and near-zero auto-compensated latency. Formats listed are VST3, AU, and AAX on Windows 10+ and macOS 10.13+. The one-time price is €2,499 as a one-time purchase. A Windows and Mac demo is available, but its volume turns down every 30 seconds and host automation is unavailable. The product page states free updates and a 15-day money-back guarantee.
