HoRNet Butterfly is a comprehensive audio mastering plugin crafted to deliver professional finishing touches to stereo mixes and mastering projects. It integrates high-quality processing modules inspired by advanced mastering tools, offering an equalizer, compressor, clipper, and limiter within a single interface. These elements are designed to provide precise control over your sound, ensuring clarity and polish in the final output.

The plugin's processing modules are based on proven technologies, guaranteeing exceptional audio quality enhanced by intelligent oversampling that maintains a pristine signal without artifacts across various sample rates. Users can easily customize the processing chain by rearranging module order to suit their workflow. A built-in LUFS metering section provides detailed input and output level readings, including momentary, short-term, integrated, and true peak measurements, supporting informed mastering decisions.

While optimized for stereo buses, Butterfly’s flexible design allows operation on mono channels, functioning as an efficient channel strip. Each module can be independently bypassed to optimize CPU usage, though the plugin is inherently light on system resources, enabling multiple instances without strain. Compatible with macOS and Windows, supporting various plugin formats, and featuring a resizable, hardware-accelerated interface with Apple M1 support, HoRNet Butterfly offers a powerful and user-friendly solution for mastering engineers and producers.
