基于声卡和MATLAB的音频信号的采集和处理
Collecting and Processing of Audio Signal with MATLAB and Soundcard
【摘要】 MATLAB是数据分析和处理功能都非常强大的工程实用软件,可以灵活地驱动声卡采集和处理音频信号。本文探讨了基于声卡和MATLAB的音频信号采集和数据处理方法,并结合古琴音板音频检测的应用实例进一步证明:利用声卡做主要硬件,MATLAB做软件进行音频信号的采集和处理不仅简单可行,而且编程处理方便,可以广泛应用于音频检测等工程领域。
【Abstract】 MATLAB can drive soundcard to collect and process the audio signal smartly with its huge function of data analyzing and processing.The method of collecting and processing of audio signal with soundcard and MATLAB software is discussed in this paper.A case of using audio signal to detect the soundboard of ancient qin is combined to prove that,this method have been widely applicated in the engineering fields for its simpleness and conveniency.
