I've uploaded my tracking simulation paper here. It is not the same PDF as what you would download from aes.org; an added footnote to the paper reads:
This is a revised version of the preprint presented at the 127th AES convention in October 2009, and available from the AES. That preprint remains the authoritative version of this text. Here, the copyrighted AES logo and other convention livery are removed, but the contents of the paper are unmodi ed.
