This is an audio visualizer for microphone data using Web Audio.

The user interface supports the following controls:

  • Switching between viewing the audio frequencies and waveform spectrum
  • Changing the length of history data stored (try lowering this if there is lag)
  • Changing the hue factor which is multiplied by the magnitude to determine the color
  • Changing the alpha transparency of the graph

Audio-related functionality based on https://webaudiodemos.appspot.com/ and style inspired by http://jonathanwatmough.com/2008/02/prototyping-code-in-clojure/.
