// LiveInput example for Processing V90
// Description: Shows FFT spectrum and volume level for the active sound-input on your mahcine.
// For PC: use the 'Sounds & Audio Devices' menu in the control panel to choose your input; Mic, wave, etc.
// For Mac: the current microphone device will be used as input.
