FUSER vs HoRNet ZeroBus

FUSER is an audio plugin that detects frequency clashes between tracks and reduces them dynamically, helping competing parts occupy space in a mix. Resolve Conflicts processes detected channel conflicts and frequency masking automatically. Phase Analyze identifies a phase rotation intended to reduce cancellation between layered sounds. Users can adjust mid/side, Q, attack, and release controls, and listen to the Delta signal. FUSER supports stereo processing and offline file analysis, with views for loudness, peaks, stereo balance, phase correlation, dynamic range, loudness range, and tonal balance/EQ. It runs on macOS 10.15 or later and Windows 10 or later; the Mac version is native for Apple Silicon. Mac hosts can use 64-bit AU, VST 3, or AAX, while Windows hosts can use 64-bit VST 3 or AAX. The listed price is £59 as a one-time purchase, and the maker offers a fully functional 15-day trial. A 30-day money-back guarantee is also listed, subject to deactivation and a support request within 30 days of purchase.

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.
