Tests for this particular part are tricky. We still have the SBR issue 
where we add a single sample of delay to the output, which the reference 
samples and their decodings do not. Adding a test would mean modifying 
the samples in a way where we would not be able to use them after fixing 
this (in addition to all the other regular AAC samples with SBR we have 
that would become irrelevant).

My plan is to fix this after this patch, as its a troublesome topic.
