In their own words
Open Audio Analyzer
Open Audio Analyzer is free, open-source software for measuring loudness and spectrum in live audio and audio files. Its fourteen meter types include loudness, true peak, VU, spectrum, spectrogram, oscilloscope, phase scope and histogram. Loudness measurements follow EBU R 128 and ITU-R BS.1770-4, with momentary, short-term and integrated LUFS, loudness range and oversampled true peak. Users can arrange meters across tabs, save presets, choose delivery targets for streaming or broadcast, and create their own targets. A command-line tool analyzes individual files or album folders and can produce reports or CSV output. VST3 and Audio Unit plugins send measurements and DAW transport position to the app. An AAX plugin is in the plugin archive but is not signed for a released Pro Tools version. A tablet on the same network can display the app's published measurements over Wi-Fi. The maker says measurements stay on-device and audio is neither stored nor transmitted. The remote display link has no encryption or authentication. The app runs on Android, iOS, Linux, macOS and Windows.
