An embedded digital audio processing device

Abstract

The invention provides an embedded digital sound processing device, which comprises an audio input unit, an audio processing unit and a singlechip microcomputer. The audio input unit is electrically connected to the audio processing unit, and the audio processing unit is electrically connected to the singlechip microcomputer. The audio input unit receives an audio signal and sends the audio signal to the audio processing unit; a first sound processing chip in the audio processing unit performs gain superposition on each path of input, and an audio signal A generated after the superposition is sent to a second sound processing chip after sound processing; the second sound processing chip comprises an analog switch, an audio signal processed by a PC end sound card and the audio signal A are synthesized to be a signal B, and the run of the signal B is chosen by the analog switch; the singlechip microcomputer is electrically connected to the analog switch, and is used for controlling the audio signals to be sent to sound equipment to be output, and controlling the analog switch to choose the audio signals to output to a recording unit for recording. By the device, multiple people can enjoy professional sound processing effect when singing karaoke at home, and the device is light and convenient to carry, and can provide multiple recording modes.
