随着信息产业数字化的发展,广播电台越来越趋向于数字化,使用数字设备录音,使用数字播出设备取代模拟设备,基本上数字信号为主模拟信号为辅。如何测量数字信号的指标,判断数字设备的性能成了当前需解决的问题。文中着重谈了如何使用音频测试软件测试数字信号及设备。
With the development of the digitization of the information industry, radio stations are becoming more and more digitalized. They use digital equipment to record audio and use digital broadcasting equipment to replace analog equipment. Basically, digital signals are mainly supplemented by analog signals. How to measure the index of digital signal and judge the performance of digital equipment has become the current problem to be solved. The paper focuses on how to use the audio test software to test digital signals and equipment.
