Adding a loop of a specific post format

I am trying to add a second loop to a canvas (from woo themes) child theme. (the site can be viewed here http://wpgu.illinimediaadvertising.com/)

I want to display a loop of just the audio below the slider (http://maryfranwiley.com/b/portfolio/secret-project-1/) to highlight the audio content. I am fully capable of styling the elements. It is just that I am not sure if I should be editing the magazine template files, or if adding a loop via the woo_loop_before hook is the way to go (and if it is, what I did wrong)

Here is the function that I added to the child theme’s functions.php http://pastebin.com/1dtyrRDW
