This lib (or demo) does the following things to simulate a chat between a browser and a server:

1. Browser detects any voice activity, records and sends speech s1 to Server;
2. Server receives speech s1;
3. Server constructs and sends speech s2 to Browser;
4. Browser receives and plays speech s2.

Notice Browser won't record and play at the same time, thus there is a queue.

Notice Server should save all speeches with userId and timestamp.

$ npm install

$ npm start

Open 127.0.0.1:3883.

Great work from:

1. browser-pcm-stream
2. vad.js
3. socket.io
4. binary.js
