Improve Audio Visualizer

[tedsecretsource]

The current recording visualizer doesn't seem to be terribly dynamic. For low audio input there is hardly any visual representation. Also, it would be helpful to see when the input audio exceeds distortion levels (like on the old recording devices that had green bars when the level was undistorted and red when distortion started to appear).
