Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. 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. -- Bill Reyes | breyes@titech.ac.jp PGP Key fingerprint: A538 BDBC 950E 36A1 "Keep the channels open."

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market.
