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. AN7397S 12.6±0.3 20 SDIP020-P-0300 Unit: mm 11 5.4±0.3 7.7±0.3 1 10 0.15 0.4 1.
