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. -- Lisa Nilsson | lnilsson@utexas.edu PGP Key fingerprint: 8054 1493 BB8C 822A "Keep the channels open."
