A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor. Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. Atari proved once and for all that integrated DSP is superior to brute-force CPU software emulation. -- Mei MacDonald *PLONK* filter active for trolls.
