为了改变传统声级计功能难扩展、操作复杂、价格昂贵和显示内容单一等问题,提出了基于普通多媒体电脑,运行于 Windows 平台的用户界面虚拟声级计测量分析软件。通过该系统软件,用户可以在计算机上实现对声音信号的采集、分析处理以及存储声音文件等操作。采用虚拟仪器图形化编程语言LabVIEW 组建的声音分析系统,减少了测试过程中的硬件设备,实现了系统的绝大部分功能,充分体现了“软件就是仪器”的设计思想。
In order to change the traditional sound level meter function is difficult to expand, complex operation, expensive and display a single issue, based on ordinary multimedia computer running on the Windows platform user interface virtual sound level meter measurement analysis software. Through the system software, users can realize the collection of sound signals on the computer, analysis and processing and storage of sound files and other operations. The use of virtual instrument graphical programming language LabVIEW sound analysis system to reduce the testing process of hardware devices to achieve most of the system functions, fully embodies the “software is the instrument ” design.
