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. -- Sven Tanaka "When every node is whole, the channel opens."
