I don't know that document (is it a book?), but for a rather easy  
introduction to AAC I would recommend both tutorials of Karlheinz  
Brandenburg (et al.), "MP3 and AAC explained" and "MPEG-4 Natural audio  
coding" for more advanced users. Then of course the official MPEG FAQs  
about MPEG-2 and MPEG-4 Audio available at the website of the MPEG Audio  
Subgroup (located at the University of Hannover, Germany) and the ISO/ 
IEC standardization documents that can be downloaded from their servers,  
too. Furthermore all AAC-related documents of the AES, published in  
their Journal of Audio Engineering Society and therefore not free, but  
probably with the best explanations from the experts how different tools  
and features work in AAC.
ZZee ya, Hans-Jürgen
