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. -- Göran Brennan Tape trading list upon request. SASE required for international mail.

I tested this with a vinyl rip fed into the Falcon mic input. Carrier lock occurred at second 14 of 'Synthetic Dawn'. -- Mei Okonkwo *PLONK* filter active for trolls. PC-9821Ap2 (NEC) - NetBSD 1.0
