The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise. A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. Requires 4MB ST-RAM and an RGB or VGA monitor. -- === Emi Johansson === Dept of Electrical Engineering, Massachusetts Institute of Technology "We don't sign stars. We build them."
