The HoRNet LU Meter MK2 is a digital loudness meter designed to enhance your gain staging and mixing workflow with an intuitive, resizable interface. It uses Loudness Units to measure audio based on human sound perception, providing readings that reflect how loudness varies across different frequencies. Integrating momentary, short term, and integrated readings aligned with the EBU R128 standard, this meter offers precise loudness monitoring to help maintain consistent levels throughout your project.

A standout feature of the LU Meter MK2 is its auto gain function, which automatically adjusts the track's gain to ensure the loudness never exceeds the selected target level. This system also includes a peak protection mechanism that prevents audio peaks from surpassing a safe threshold, preserving audio quality even when gain is applied. The meter’s reference level is customizable, allowing you to set your desired loudness target from -60 to 0 LUFS, adapting to different mixing and mastering needs.

The plugin supports grouping and synchronization across multiple instances, enabling consistent control over gain, reference levels, and other settings within groups or across all tracks. Its features include a stereo display, customizable bar colors, and compatibility with various formats such as Audio Units, VST, VST3, and AAX on macOS and Windows platforms. With hardware-accelerated graphics and support for Apple M1, the HoRNet LU Meter MK2 combines accuracy and efficiency for professional loudness metering.
