摘　　要：针对传统音频分析设备存在的问题,基于模块化设计思想,在LabVIEW开发环境下,依据PC机普通声卡进行信号的采集与分析,设计了音频信号分析仪。为保证音频分析仪在不同环境中使用,又开发了脱离LabVIEW环境的音频信号分析引导程序,使音频信号分析仪能够跨平台操作。经过在不同操作系统上的测试表明,该音频分析仪具有可扩展性好、适应性强、成本低廉、准确度高等优点。The audio signal analyzer in LabVIEW development environment is designed, with. modular design concepts is designed, and PC ordinary Sound card for signal collection and analysis is used, it overcomes the problem existingin traditional audio analysis equipment. At the same time, in order to ensure the designed audio analyzer can be used in different environments, guide procedure for audio signal analyzer is developed which can run without installing LabVIEW, so the audio signal analyzer can achieve cross-platform operation, After testing on different operating systems, the result shows that the audio analyzer has advantages of good scalability, adaptability, low cost, high accuracy and so on.
