Taking advantage of the Falcon's built-in 32 MHz DSP56001 and 16-bit audio codec.

Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard.
A 256-point complex FFT is computed every 10 milliseconds, displaying a live spectrogram on a standard VGA monitor.

Atari Falcon vs Amiga 1200 flamewar in 3... 2... 1...

Unsubscribe me from this list! (Wait, this is Usenet, never mind).

The SSI to DSP56001 architecture on the Falcon is magnificent. Zero CPU overhead during 50 kHz audio acquisition.
