I'm trying to write a piece of code that fetches the url/download link of any embedded audio files in the current post. In doing this I stumbled upon get_attached_media which outputted something like this (I have removed some of the values in order to keep it short):
Array (  => WP_Post Object ( [ID] => 172 [post_author] => 1 [guid] => http://localhost/wp-content/uploads/2013/07/03-take_me_out_128_lame_cbr_ex.mp3 [menu_order] => 0 [post_type] => attachment [post_mime_type] => audio/mpeg ) )
As you can tell it is all wrapped in this "WP_Post Object". Now, I'm sure this is all common place and fairly simple to resolve, but I can't figure out how. Essentially, what I want to do is to fetch the "GUID" value and attach it to a variable, as it seems to contain the URL of the post's embedded audio file.
Also, please correct my terminology so I can make this question more useful to others who migh seek an answer to this.
