The HoRNet LU Meter is a digital loudness meter designed to enhance gain staging and mixing through an intuitive interface. It measures audio using Loudness Units, which account for human perception by varying readings based on frequency, providing a more accurate representation of perceived loudness. This approach allows for improved control over audio levels, making it easier to balance tracks and masters according to how they will be heard.

This meter incorporates the momentary loudness measurement from the EBU R128 standard and applies an auto gain function to maintain the signal within a chosen Loudness Unit level. Users can normalize tracks based on momentary or integrated loudness readings, with added peak protection to prevent signal peaks from exceeding set safety limits. The plugin offers flexible metering options, including separate left and right channel meters or a summed stereo mode, and allows customization of reference levels to suit different mastering or mixing needs.

Compatible with both Mac and Windows systems, the HoRNet LU Meter supports multiple plugin formats such as Audio Units, VST, VST3, and AAX, ensuring broad usability across digital audio workstations. It features stereo automatic gain adjustment with various settings, assignable group controls, and customizable display elements, making it a powerful tool for achieving consistent loudness and dynamic balance in audio production.
