AN7399S
Spatializer sound processor IC
I Overview
A spatializer audio processor is the Desper Inc.'s
proprietary signal processing technology exclusively
developed for the consumer electronics and multi-
media market. It is based on the Desper's profes-
sional 3D audio production system "PRO-
Spatializer". You can enjoy a sound enhancement and
extension effect with the conventional two-speaker
stereo system by using the innovative technology
adopted in this equipment.
I Features
• Fewer external parts (minimum parts count: 4)
• Wide operating supply voltage: 4.5 V to 10 V
• A sound source in the center position is necessarily
positioned in center regardless of the spatializer
effect value.

I Conceptual Description on Spatializer Operation
• Stereo normal mode
All sound are heard from between both left and right
speakers.
• Conventional surround system
Sound expands outside the speakers but the sound
position is not stable.
• Spatializer
The sound expands outside the two speakers and
the sound position is stable.
The sound come to have its expansion and depth.
And also, a sound source in the center position is
necessarily positioned in center regardless of the
spatializer effect value.
I Usage Notes
1. Do not apply 0.3 V or more to pin 12 because it relates with pin 13 (VCC pin)
2. If more than 0.3 V is applied to pin 12, the current flows to pin 13 (VCC pin) via a surge protection diode connected
to pin 12.
