Audio signal processing method

Abstract

The invention belongs to the field of audio signal processing methods and provides an audio signal processing method. The audio signal processing method relates to a collecting module, an amplifying module, a filtering module, an analog-to-digital conversion module, a processing module and a digital-to-analog conversion module, wherein the collecting module, the amplifying module, the filtering module, the analog-to-digital conversion module, the processing module and the digital-to-analog conversion module are connected in sequence, and the processing module is further connected with a storage module. The collecting module is used for collecting and obtaining audio signals, filtering processing is carried out on the audio signals through the filtering module after signal amplification processing is carried out on the audio signals through the amplifying module, the analog-to-digital conversion module is used for converting the audio signals input from the filtering module into digital signals, and the processing module is used for carrying out signal processing on the digital signals and sending the digital signals to the digital-to-analog conversion module to output analog signals. According to the audio signal processing method, high-quality audio messages can be obtained under a noisy environment, and the requirements of audio-visual equipment and audio equipment for high-quality audio signals under different noisy environments can be met.

Description

technical field [0001] The invention belongs to the field of audio signal processing methods, in particular to a method satisfying high-definition voice audio signal processing. Background technique [0002] Audio equipment often has noise when acquiring voice information. These noises include environmental noise from the surrounding environment, which can also be called background noise, and electronic noise from the audio equipment itself. These noises can affect the quality of the audio signal. For audio in HD quality people often build recording studios for audio acquisition. However, it is difficult to obtain high-quality voice information without a recording studio, especially in outdoor, road and other occasions; it is a technical problem to acquire and analyze people's voice information in a noisy environment. [0003] In the past, the processing of audio signals was only in the state of analog signals. With the advent of the digital age, especially the development...
