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

The DSP56001 processes the 44.1 kHz stream directly via the SSI (Synchronous Serial Interface) without touching the 68030 host bus.
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.

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

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