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. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Fiona Takahashi "Hold for relay."

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market. -- === Lucia Tanaka === Dept of Electrical Engineering, Demon Internet Services UK "Hardware is temporary.
