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