{"version":"1.0","type":"rich","title":"Sampler using Web Audio","description":"This interactive audio sampler displays a waveform of an imported WAV file and divides it into eight equal sections. Users trigger playback from any section by pressing the corresponding number key or touching the waveform on mobile devices. A red line animates across the waveform to show playback position while the active section highlights in blue. The visualization uses d3.v4 for SVG rendering, transitions, and scales, alongside the Web Audio API for audio decoding and playback. A stop button resets the playback position and highlights.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-5e4b763bf399027de8c110086c74eba0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
