音频的数字化处理技术探究

Research on digital audio processing technology

随着计算机网络技术的发展,音频的数字化处理技术的应用越来越广泛。本文阐述了音频信号的定义,并从音频信号的采集、量化、编码、压缩、噪声处理、提取、抗混迭滤波等方面对音频信号的数字化处理进行了阐述。通过本文的分析论述对音频数字化技术有了全面的认识,为其应用奠定了理论基础。

With the development of computer network technology, digital processing technique is applied more and more widelyin the audio. This paper introduces the definition of the audio signal, and from the collecti on, quantization;encoding, compression, noise processing, extraction, anti alias digital processing stack filter and other aspects of the audio signal to audio signal is discussed in this paper. Through the analysis of this audio digital technology has a comprehensive understanding, to lay the theoretical foundation for its application.
