The Atari Falcon also had, like its predecessors, special chips that gave it its power. What made the Atari Falcon a very special machine for its time was that Atari had built in a DSP for much faster operations. The blitter chip for fast graphics editing was also thrown up in speed.
Regarding sound, Atari decided to build in a codec that would allow the computer to reproduce 8 sound channels at 50 kHz. People could then make this audible again on an amplifier with speakers. A microphone was also built in. However, users were annoyed with the audio connections, as they wanted a normal line input and output.
The Falcon is the ultimate Atari ST and a dream machine for many people. Not many were sold at the time and the machine is now considered very rare.
