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. - 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.)

Could you build this?
Partial While basic web audio visualizers are straightforward to vibe-code, implementing advanced DSP algorithms like the reassignment method for spectrograms and precise A-weighting filters requires specialized digital signal processing knowledge.
What it would actually take: A full version requires Web Audio API or WebAssembly (compiled from C++ or Rust) for performance-critical DSP operations, paired with Canvas or WebGL for 60fps rendering. The challenging piece is implementing mathematical transforms like the time-frequency reassignment method (computing phase derivatives and mapping energy) and standardized acoustic weighting filters accurately. Success requires solid expertise in digital signal processing and fast numerical computation.
