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. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Raj Kuznetsov SupraFAXModem 28.8 @ 28,800 bps "Tape doesn't lie at 02:14. Ears do."
