10:42:33 # Life I wanted to learn about audio spectrograms of instruments. I wrote a web app because I could. Not sure if I should be fine-tuning some of the axes yet because I haven't looked at many actual waveforms to know if this is useful. But here is the web app. Handles the default input only, and discovered that my electric piano sound is not picked up via USB C and maybe I need to add some configuration option.
