摘要
基于计算机声卡和Adobe Audition软件制作了声学虚拟仪器,可实现示波器、信号发生器和频率计算仪器功能,并介绍了此声学虚拟仪器在双音多频信号DTMF的研究、声速的测量和变音钟实验中的具体应用.
Based on the computer sound card and Adobe Audition software, the acoustic virtual instrument is made that can implement the function of oscilloscope, signal generator, cymometer, and so on. The specific applications of the acoustic virtual instrument in DTMF signal experiment, the voice velocity measurement and the experiment of change voice bell are introduced.
