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. -- Elaine Nakamura | enakamura@illinois.edu PGP Key fingerprint: C9B2 E07E F50F A737 "Keep the channels open."

The SSI to DSP56001 architecture on the Falcon is magnificent. Zero CPU overhead during 50 kHz audio acquisition.
