PRODUCT OVERVIEW
The AD1953 is a complete 26-bit, single-chip, 3-channel digital
audio playback system with built-in DSP functionality for speaker
equalization, dual-band compression/limiting, delay compensa-
tion, and image enhancement. These algorithms can be used to
compensate for real-world limitations of speakers, amplifiers,
and listening environments, resulting in a dramatic improvement
of perceived audio quality.
The signal processing used in the AD1953 is comparable to that
found in high end studio equipment. Most of the processing is
done in full 48-bit double-precision mode, resulting in very good
low level signal performance and the absence of limit cycles or
idle tones. The compressor/limiter uses a sophisticated two-band
algorithm often found in high end broadcast compressors.
