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. -- Tomas Dubois | tdubois@unam.mx PGP Key fingerprint: F392 CE2F A5EA A50E "Keep the channels open."
