ScienceProg presents this AVR based TDA7313 Audio processor control with every detail you need to build it. The project makes use of the TDA7313 Audio processor for its well established position in the industry and because of its simplicity, functionality and good parameters like low distortion, low noise. TDA7313 features 3 stereo inputs which allows you to link 3 separate input sources. The main idea of this project was to construct independent audio processor which can be embedded in any audio system with ability to control settings with simple button interface with menu preview in LCD.
