The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise. 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. -- Heather Kuznetsov SupraFAXModem 28.8 @ 9600 Telebit bps "When every node is whole, the channel opens."
