This patch needs two files in the fate samples:

The audio part of the Sintel movie, as a source, because I wanted to test 
with a real world example, with proper length. And the reference 
file. Sources can be generated like this:

wget http://media.xiph.org/sintel/sintel-master-st.flac
ffmpeg -i sintel-master-st.flac -codec aac -b 96k fate-suite/aac/sintel.aac
ffmpeg -t 30 -i fate-suite/aac/sintel.aac -af loudnorm=i=-23 -f s16le -ar 44100 fate-suite/filter/loudnorm-simple.pcm

Due to the 96k AAC codec, sintel.aac is about 15M, loudnorm-simple.pcm is 
around 6M. Still a bit big, but IMHO it is ok to add these to the 
fate samples.

Marton
