Thanks. It was my audio input.

For others having a problem with this example:
for the ESS library – make sure you restart processing after you extracted
for the audio input in windows – turn on/unmute stereo mix as input, in volume settings.

If your not getting any errors it’s probably an issue with your audio input. The script checks for the default audio input. My computer has in internal microphone. Check the sound settings in your system preferences and make sure it’s picking something up and the input volume is turned up.

If your still not getting anything you can try scaling up the signal within processing by increasing the fourth parameter of the renderSpectrum function (currently 400) within the draw loop. Other than than that it might help to yell at your computer.

Tried it out, all I get is a white background, with a few very small gray dots.
