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. -- === Liam Andersson === Dept of Electrical Engineering, UC Berkeley Department of EECS "Hardware is temporary.
