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

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.

Too bad Atari marketing was so incompetent that nobody bought the Falcon before they pulled out of the computer market.
