天气雷达回波产生 这个代码是自己编的 我用过没什么问题-Weather radar echo generated for this code is its own no problem, I used

Program that implements echo watermarking. The basic idea is to embed a watermark by adding an echo to the original sample.

利用人耳朵的时域掩蔽效应，实现回声隐藏。-Using human ear temporal masking, to achieve echo hiding.

客户端之间发送PING报文，客户端接受其他客户端的PING报文，回复信息。 个人想法：通过UDP连接，客户端与服务器建立连接，登录只要用户名（不能重复），能从服务器查询在线用户。-There are four main components to phase 2: 1) Add functionality to send “ping” messages over UDP and listen for echo responses, in order to
