AN7397S

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. AN7397K 19.1±0.3 20 11 Unit: mm 6.35±0.30 1 10 1.1±0.25 3.45±0.25 4.50±0.25 1.778 0.9±0.25 0.5±0.1 3° to 7.62±0.25 1 5° 0.35 – 0.05 +0.1 ■ 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.
