+www.deviantart.com/view/*
-www.deviantart.com/view/*/?*
+images.deviantart.com/*.gif
+images.deviantart.com/*.jpg

line one excludes ALL files
line two includes all files under the www.deviantart.com 
domain in and bellow the view folder
line three excludes all files one level bellow 
www.deviantart.com domain's view folder
and lines four and five include .gif and .jpg files on 
images.deviantart.com subdomain

in your case (let us asume the domain is www.testing.com)
you should exclude all files
-*
and then include audio files
+www.testing.com/audio/*.mp3
+www.testing.com/audio/*.wav
+www.testing.com/audio/*.au
and also images
+www.testing.com/images/*.jpg
+www.testing.com/images/*.jpeg
+www.testing.com/images/*.gif

hope this helps.
also be sure to get the site path (url) right for both 
audio and images. you will need to try it a few times just 
to get the hang of the filters. i know i had to.

i know xavier is going to be helping you anytime soon also.
so try this. if it fails ask again. :)
and read the xaviers answer also :)
