Overview
ICs for Audio Common Use AN7397K, AN7397S Spatializer IC for I2C bus ■ Overview Spatializer Audio Processor is a signal processing 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 stereo system.

1 ■ Features • Provides deep 3-D sound with conventional 2speaker 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 signal is achieved.
• Positions and moves each sound source on 270° arc in real time.
• An on-chip serial control bus (i.
e.
, I2C) to vary space-effect and change modes.
