How to run example?（体验example里的文件）
An example with simple node server script is available that include some raw pcm data that will be served by websocket and at the client end, it will be played through PCM player.
1. open server directory （进入到server目录）
` bash
cd example/server
`
2. run a local server （把本地的服务端跑起来，会起一个websocket服务，用来发送数据）
` bash
node server.js
