I'm listening to an 11 hour audio book, it's a real pain having to find the exact spot I was last. Is there a way to mark or place a sort of bookmark to the audio track?
If it is nothing but a normal audio file, you sure can. Go to the tools-tab (or whatever it is called in English) and select bookmarks. There you can set new bookmarks, delete old and jump to already set bookmarks. That should be exactly what you are looking for.
