Adding Narration Tracks
You cannot record the actual audio files in Tour Creator. You must create them outside of Tour Creator and then add them to your Tour. You can record your audio in any external audio editor.
Online Audio Recorder is free, quick, simple and works on a Chromebook.
Adding Ambient Audio Tracks
You can often find good ambient sound tracks simply by searching online with an appropriate search term like [busy restaurant soundtrack mp3]
You could also try YouTube's sound effects library
Thanks to Chris Betcher (@betchaboy) for these free audio resource suggestions!
