AN7397K, AN7397S
Spatializer IC for I
2
C bus
■ Overview
Spatializer Audio Processor is a signal process-
ing technology, monopolized by Desper Products,
Inc., that was developed for commercial electronics
and multimedia markets, and is based on Desper's
“PRO Spatializer” that is a 3-D audio production
system for business use. The AN7397K, AN7397S
utilizes the innovative technology adopted in that
system, and provides sound enhancement effect and
sound expansion with the conventional 2-speaker ste-
reo system.
■ Features
• Provides deep 3-D sound with conventional 2-
speaker system.
• The audio signal recorded through this IC can be
reproduced with usual stereo system.
• Performs optimal processing to the sound source
recorded with surround-effect so as not to give
double effects.
• Sound localization can be varied.
• A pseudo stereo effect for the monaural audio sig-
nal is achieved.
• Positions and moves each sound source on 270°
arc in real time.
• An on-chip serial control bus (i.e., I
2
C) to vary
space-effect and change modes.
■ Applications
• Televisions, videos, audio equipment, DVDs, per-
sonal computers, and game machines
