HoRNet Plugins has pulled the algorithms from the SAMP Dolby Atmos master processor and created Butterfly, an all-in-one mastering tool and channel strip plug-in. As a combination of EQ, compressor, clipper and limiter, HoRNet Butterfly offers everything you need to give your mixes the final touch.
Butterfly, the latest plug-in from developer HoRNet Plugins, not only looks similar to the company’s SAMP Dolby Atmos master tool released in February, but also uses the same processing modules. Similar to other all-in-one mastering tools, it offers a complete mastering chain in one plug-in. But HoRNet says that it’s not only for mastering, but can also be used as a channel strip.
The metering section on the left provides a real-time overview of the input and output levels. Besides True Peak values, it shows momentary, short-term and integrated LUFS readings.
The panel on the right side has tabs for the equalizer, compressor, clipper and limiter modules. The EQ is a parametric equalizer with up to six bands, an integrated analyzer and visual editing. It’s based on TotalEQ. The compressor, clipper and limiter modules all feature big controls for the most important parameter (threshold for the compressor, gain for clipper and limiter). Additional controls are accessible at the bottom of the window, where applicable. HoRNet has pulled the compressor from SyncPressor, while the clipper and limiter algorithms come from Magnus MK2.
What’s great is that you can rearrange the order of the modules by dragging the tabs. This allows you to quickly place the compressor in front of the EQ, or reverse the clipper and limiter, for example. You can also disable the modules you’re not using, in order to save CPU power.
On the whole, HoRNet certainly hasn’t reinvented the wheel with Butterfly. But the plug-in looks like a solid and comprehensive mastering processor at an attractive price.

HoRNet Plugins Butterfly is now available for EUR 37.99 from the developer’s website.
