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. -- Natalia Takahashi Zyxel U-1496E @ 19,200 bps "5 sigma is a discovery. 7 is a question."
