基于LabVIEW和声卡的声音均衡器设计

Designer of Sound Equalizers Based on Audio Card and LabVIEW

本文介绍了一种将声卡作为A/D和D/A,用LabVIEW实现声音播放、声音采集以及对声音信号做频谱分析实现声音均衡器的功能。文中设计的声音均衡器可以加深对信号采集和信号处理的理解,具有一定的参考借鉴价值。

The paper uses the audio card as A/D and D/A and introduces the design of sound equalizers based on LabVIEW,which realize sound play,sound acquisition and sound signal for spectrum analysis.The sound equalizers designed in this paper would enrich the understanding of the signal processing and also have some merit.
