Our verdict on HoRNet ZeroBus

HoRNet ZeroBus is a desktop audio plugin for music producers and mixing engineers who want automatic processing on stereo mix buses, drum buses, and other stereo subgroups. It combines continuous 31-band automatic equalization with real-time spectral balancing, adaptive compression, and automatic makeup gain. The plugin runs on Windows and macOS and is distributed in VST3, AU, and AAX formats, making it suited to compatible digital audio workstation setups.

Pricing is straightforward: the HoRNet ZeroBus plan costs €24.99 as a one-time purchase. It includes the full feature set, including automatic EQ, adaptive compression, FAT parallel 1176-style compression, GLUE serial SSL-style compression, an EQ curve and gain-reduction meter, and automatic 2× oversampling below 88.2 kHz. The downloadable demo is time-unlimited but includes periodic audio interruptions, while the product page states a 15-day money-back guarantee. This structure fits producers who prefer a low upfront cost over a recurring subscription.

Its standout feature is the combination of continuous spectral analysis and learned bus compression in one focused plugin. The FAT mode applies parallel compression, while GLUE uses serial compression, giving users two distinct approaches to shaping stereo buses. Real-time metering helps show the EQ curve and gain reduction as processing changes. ZeroBus is narrower than a complete mixing environment: its focus is stereo bus processing, not spatial processing or a broad collection of mixing tools. Choose it when automatic bus EQ and compression are the priority; choose another option when you need a wider mixing suite or processing beyond stereo subgroups.
