AN7396K
Sound signal processing with built-in Spatializer IC
a73 Overview
Spatializer Audio Processor is a signal processing
technology, monopolized by Desper Products, Inc., that
was developed for commercial electronics and multime-
dia markets, and is based on Desper's “PRO Spatializer”
that is a 3-D audio production system for business use.
The AN7396K utilizes the innovative technology adopted
in that system. It provides sound enhancement effect and
sound expansion with the conventional 2-speaker stereo
system. Moreover, the AN7396K is a sound processing IC
which incorporates the I
2
C Bus-controllable mute, sound
AGC, bass reinforcement, tone (bass and treble), balance,
and volume circuits.
a73 Features
• Provides deep 3-D sound with conventional 2-speaker
system.
• Performs optimal processing to the sound source re-
corded with surround-effect so as not to give double
effects.
• Provides the functions of muting, AGC, bass reinforce-
ment, tone, balance, and volume control.
• Supports I
2
C Bus controls.
a73 Applications
• Televisions, videos, audio equipment, and game machines
