Summary

You should now have a clear understanding of how easy it is to adapt our existing video call application to support audio only calls. You should be able to update the HTML user interface to adapt from video to audio. And you should now understand how the cleanly abstracted design of the signaling server requires no real updates to support this new application scenario.

You should also have all the information you need to start exploring how these audio streams can be processed to create filters and other special effects.

In the next chapters, we will explore how this application can be extended with text based chat and file sharing.

And then, we will explore two real-world application scenarios based on e-learning and team communication.
