OpenMeters – A fast and free audio metering/visualization suite
This has been a pet project of mine for the past ~5 months. It consists of six visualizations: - Spectrogram: Implements the reassignment method for sharper time and frequency resolution. - Spectrum analyzer: A-weighted, frequency guidelines, loudest frequency tooltip. - Waveform: Colored based on frequency, loudness, or static - Oscilloscope: Tracks pitch and autocorrelates against a reference signal, provides stability. Also includes a regular zero-crossing trigger. - Stereometer & Phase meter: Linear and exponential scaling modes, adjustable windows. Multi-band correlation meter. -…
In plain words
OpenMeters is a free audio metering and visualization suite for Linux featuring six analysis tools: spectrogram with reassignment method, A-weighted spectrum analyzer, frequency-colored waveform display, pitch-tracking oscilloscope, stereo and phase meters with multi-band correlation, and loudness measurement in LUFS and RMS. It is designed for audio professionals and enthusiasts who need detailed real-time audio analysis and visualization capabilities.

Also includes a regular zero-crossing trigger. - Stereometer & Phase meter: Linear and exponential scaling modes, adjustable windows. Multi-band correlation meter. - Loudness (LUFS & RMS): Implements the latest lufs standard. Adjustable timeframes. Let me know what you think, and give it a star if you think it deserves as much. :] (check out the readme for a more complete enumeration of its features. Currently only available on Linux.)
