That's a common misunderstanding. We store GPX tracks in two forms. One, the original GPX files, exactly as uploaded, with whatever extra private information your GPS emitted ("waypoint 001, note=this is where I kissed Joanna yesterday"). These are stored on the server, but only accessible to the public in this "full" form if you explicitly make them public. (There's an API call to retrieve lists of trace files and download the individual files if desired.) Furthermore, any uploaded track, public or not, is processed by a daemon and the individual GPS points with timestamps and a link back to the file where they came from are stored in the database. The API will, on request, return all GPS points within a certain bounding box, but you will ONLY get GPS points, ordered by timestamp but you don't see the timestamp, and you will not get the track structure or the note about Joanna. Apart from the web site where you can browse the individual tracks, all clients use the second interface that gives access to all GPS points, but not the extra data. This means that you will never be able to match an audio track to GPS points downloaded via the API "all GPS points in bbox" call, but that's probably not what you want anyway.
