In their own words
Friture
Friture is a free, GPLv3+ audio analyzer that displays signals in real time for examining audio and room or receiver behavior. Its views include a spectrum analyzer, rolling two-dimensional spectrogram, fraction-of-octave analyzer, scope, pitch tracker, delay estimator, and level display. The spectrum view shows frequency components, recent peaks, and the global maximum, with adjustable response time. Delay estimation uses cross-correlation between two input channels and works only in two-channel mode. The level view reports peak and RMS power in dBFS, using 25 ms and 300 ms response times. A built-in generator produces sine, pink-noise, white-noise, sweep, and burst signals. Downloads are offered for Windows, macOS, and Linux, including a Windows Store build and Linux AppImage. Other distribution packages or PyPI may work, though dependencies can require manual installation. Friture says it collects no microphone or personal data, uses no cookies, and does not store or analyze activity.
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.
