Description
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.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
