2-2 DNC Software Engine

Sony’s unique digital noise canceling technology and high quality audio processing technology come together in the Integrated

DNC processor to maximize the merits of digital processing, as shown in the figure.

The noise picked up by the noise detection microphone is digitalized by the A/D converter, and the optimal canceling signal is

generated through high-speed, high-precision digital filter processing by the DNC Software Engine at the heart of the processor.

After audio enhancement processing by the Digital Sound Enhancer (see page 12) via the A/D converter, the music signal from the

media player is added to the noise canceling signal in the DNC Software Engine.

The added signal is faithfully reproduced by the S-Master Full Digital Amplifier (see page 16), enabling high noise canceling

efficiency and dynamic music reproduction.
