{"version":"1.0","type":"rich","title":"A couple of changes to example4.html from this great article by Jos Dirksen (http://www.smartjava.org/content/exploring-html5-web-audio-visualizing-sound) are sufficient to get it running in Firefox Aurora.","description":"This example visualizes the frequency spectrum of live audio input, displaying animated bars that respond to the sound’s amplitude and frequency. It works by using the Web Audio API’s `AnalyserNode` to capture real-time data, then rendering the waveform with Canvas 2D drawing. The code includes compatibility fixes for Firefox and Chrome, switching from `createJavaScriptNode` to `createScriptProcessor` and from `noteOn` to `start`. The visible rendering loop updates bars based on the analyser’s frequency data, driven by a `requestAnimationFrame`-style callback.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-6653652?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
