Audio visualizer shader

[yigithanyucedag]

Hello, I'm trying to do audio visualizer with shader like this: https://www.shadertoy.com/view/XlcXDX

In this shadertoy example, the creator use the sound as texture. How can it be done in React Native with using react-native-skia?

This is a really cool use-case I'm actually not 100% sure how shadertoy does this.
That being say, I am wondering if a tool like wav2png is the way to go: https://www.npmjs.com/package/wav2png

I should also mention that in shadertoy, the goal is to provide a no-setup UI and there using sound as a texture is just clever. In RN Skia you do have control over the setup and you could inject the audio data as a uniform at your convenience. However I must disclaim that I am not familiar with this topic yet.
