The easiest way to add audio to a map tour is to upload your audio track to a web service that allows you to host and embed an audio player in an external website (something like SoundClound). Then, when you add a new tour point, choose "video" then "other" (see this blog post for help: http://blogs.esri.com/esri/arcgis/2014/01/21/adding-websites-to-your-story-map-map-tours/). Instead of using the website's url, you should use the embed code source URL.For Example, on Sound Cloud, if you click a audio track and click share, then click "Embed" you will be given this code:<iframe width="100%" height="450" scrolling="no" frameborder="no" src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/131830246&auto_play=false&h..."></iframe>Only use the URL highlighted in red.If you would like to do anything beyond this embed capability, you will need to download and modify the source code.
