Coding a 3D Audio Waveform Visualizer with JavaScript + Three.js
In this game dev experiment, we go over building a 3D audio waveform visualizer using Three.js + React + Web Audio API. We start off by setting up the React project with Tailwind CSS. Then we get audio frequency data from the HTML element using the Web Audio API and send that to the Three JS shader material. Finally, we update our vertex and fragment shaders for every frame and display the audio waveform in 3D.
