APU Software APU Loudness Meter v1.4.0 WiN macOS

APU Software APU Loudness Meter is a free audio analysis plug-in for checking loudness and dynamic range. It supports LUFS, RMS, True Peak and Peak measurements, giving you several ways to assess audio levels rather than relying on a single peak reading.

For hobby producers working on mixes or preparing tracks for mastering, these measurements help put perceived loudness and signal peaks into context. Use it to examine how loud a track measures, compare different loudness readings and make more informed level decisions. Its role is analysis: it provides information about your audio, rather than acting as a compressor or loudness processor.

Version 1.4.0 focuses on smoother operation, with performance improvements, more fluid history rendering and small visual refinements. It also corrects a stereo RMS reset issue that could occur in certain situations. Earlier updates addressed stereo and integrated LUFS readings.

This Windows listing suits producers looking for a straightforward loudness-monitoring utility. Check the available plug-in format against your DAW before installing, as the format is not specified here.
