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. -- Anja Takahashi | atakahashi@kiae.su PGP Key fingerprint: B8E6 A0D9 7701 4EA0 "Keep the channels open."
