It had always fascinated me how speech and words had such distinct features. Looking at spectrograms is essentially like hearing with your eyes.
Over the weekend i built a tool to visualize your own audio into a spectrogram in 3D. I used threeJS with shaders and vanilla JS/Html.
Play with it here : https://spectrogram-threejs.vercel.app/
I hope it brings you as much joy as it does for me.
