An audio processor is an electronic device or integrated circuit (IC) that is designed to manipulate and enhance audio signals. It performs a variety of functions to modify audio signals in ways that improve their quality, optimize their performance, or add special effects. Audio processors are used in a wide range of applications, including music production, sound reinforcement systems, consumer electronics, and communication systems.

Description

CD3313 is an audio processing circuit with volume, tone (bass, treble), balance (left, right) and loudness (front, rear) controls, suitable for high-quality car receivers, audio players and high-fidelity audio systems . This circuit provides input gain selection and local loudness control. All controls are operated through a serial I2C bus that can be connected to a microcomputer; various AC amplitude-frequency characteristics can be set through the cooperation of an external resistance-capacitance network and an internal operational amplifier. […]
