摘要
为解决Morse报的声音信号的采集存储和记录回放问题,根据Morse报的声音信号产生特点,结合音频捕捉技术和面向对象的设计思想,设计了基于DirectShow音频捕捉和基于格式化文本记录声音信息两种方案,实现了使用声卡捕捉音频和利用报文声音结构特征模拟报文声音的记录回放功能,并对两种方案的优缺点和应用环境进行了对比和分析,最后给出了具体的软件设计流程图和时序图。通过实际回放效果验证了两种解决方案的可行性。
To solve the problem of the Morse signals collection and conservation, according to Morse signals character, combining audio catch technology and open-to-design antilogy, recovered audio based on DirectShow and Morse signals character based on text storage are designed.Catching audio from sound blaster and simulating the Morse signals sound from telegraph character are realized.The merits and demerits between the two methods are analysed and compared.At last, flow chart and essential program are listed.To validate feasibility of the two methods from the effect of audio replay.
