Profile

I built a free and open-source, high-resolution, real-time audio visualizer on the web.Try it out here: https://audiovisualizer.orgThe main feature is a very high resolution frequency domain visualizer. It even works in realtime with the microphone.The application also features a synthesizer that can be played with the keyboard or MIDI files and allows for adjustable harmonics and ADSR envelopes.I used React.JS as the framework, P5.JS for rendering the visualizations, the WebAudio API for audio analysis, Meyda.JS and Essentia.JS for feature extraction, Tone.JS for synthesis, and Spotify's Basic-Pitch ML model for note transcription.It’s open source under AGPL-3.0. Feedback is welcome! GitHub

Audio Visualizer – High-Resolution Audio Visualization Tool is positioned in show hn launch, a segment that rewards a clear, focused offering.

Directory data places it at the Show HN launch stage.
