This post is part two of a series on how to build an app with spatialization features using Daily's real time video and audio APIs. The application entry point, index.ts, registers the entry form listener and joins the room once the form is submitted. The Room class contains a Daily call object and is responsible for all communication with Daily. It has methods such as join(), setBandwidth(), handleJoinedMeeting(), and more that are used to configure the spatialization features of the app. These include handling participant updates, broadcasting presence, and removing remote participants.
