{"version":"1.0","type":"rich","title":"My Test Video","description":"This example shows a video element playing an MP4 file while its audio is amplified to twice the normal volume. The page loads a local video and applies the amplification through the Web Audio API, using `AudioContext`, `createMediaElementSource`, and a `GainNode` to boost the signal. The `createAmplifier.js` script defines a function that connects the video’s audio source to a gain node set to a multiplier of 2, then routes it to the destination. The interface relies on standard HTML5 `<video>` controls, with no external visualization libraries beyond the browser’s native audio processing.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-c9f329da840680defb5b775a390cc19c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
