ICs for Audio Common Use
AN7396K
Sound signal processing with built-in Spatializer IC
I
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.
