HoRNet MasterTool is a sound processor designed to provide the perfect finishing touch to your audio tracks. It functions as an intelligent mastering assistant that adapts seamlessly to various music genres. Whether you're working on music production or need to enhance spoken content like podcasts and voiceovers, MasterTool offers tailored processing to improve clarity and balance.

The plugin addresses common mixing challenges by automatically correcting frequency spectrum issues using a frequency unmasking algorithm. It then evaluates the dynamic range of your mix and applies a sophisticated combination of a clipper and two limiters. This process effectively controls peaks, increases perceived loudness, and achieves the target output level, ensuring your audio sounds polished and professional.

MasterTool features automatic EQ analysis and correction, three dynamic processing stages, and a specialized voice mode designed for spoken word content. Users can customize LUFS target levels and the amount of EQ correction, while monitoring real-time gain reduction and frequency adjustments. The plugin supports multiple formats including VST2.4, VST3, Audio Units, and AAX, and runs on both Mac and Windows platforms with a resizable interface and hardware acceleration.
