According to expensive audio analysis instrument, based on the above analysis, this paper uses LabVIEW to design the audio analysis instrument, which uses sound card as a general data acquisition equipment of the audio signal acquisition. The contents include the audio acquisition, the audio parameters measuring, the audio spectrum analysis, etc. Test implies that the audio analysis instrument has lovely graphics and good visual effect.%音频分析设备昂贵、更新周期长、可扩性差,为此,基于计算机网络中的声卡,利用虚拟仪器思想,借助LabVIEW开发了音频分析仪,内容包括音频的采集和存储、音频的参数测量、音频的谱分析等.测试结果表明,该音频分析仪丰富了计算机网络实验功能,画面形象生动,视觉效果明显.
