Audio special-purpose integrated circuits (ICs) are electronic devices designed to process, amplify, or modulate audio signals for specific applications or functions. These ICs may include audio amplifiers, codecs, digital signal processors (DSPs), audio interfaces, and audio effect processors tailored to meet the requirements of audio applications such as consumer electronics, professional audio equipment, automotive infotainment systems, and telecommunications devices. Audio special-purpose ICs offer features optimized for audio processing, including high fidelity, low noise, efficient power consumption, and integration with audio peripherals and sensors.
