A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise.

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

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- === Amy Ito === Dept of Electrical Engineering, Delphi Internet Services "Tape doesn't lie at 02:14.
