{"version":"1.0","type":"rich","title":"SpectrogramJS","description":"This interactive spectrogram visualizes audio frequencies in real time, displaying a scrolling heatmap of sound data across time. The project uses the Web Audio API to analyze audio buffers and D3.js (v5) for rendering the SVG axes and canvas-based spectrogram. Playback controls allow users to load and analyze sound files, with the frequency analysis performed via `AnalyserNode.getByteFrequencyData`. The visualization animates as audio plays, building up the spectrogram view.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/add39f31326947478f4de9e76d6eb14a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
