Hi,
If someone needs more recent audio reference code for MPEG4 (and is not 
an MPEG member), here is how I found it. I am still not sure if it's 
ment to go public, but anyone can check it out:
Here is SC29 (subcomittee 29) page:
http://www.itscj.ipsj.or.jp/sc29/
Clicking on the BALLOT link will lead you to the page:
http://www.itscj.ipsj.or.jp/sc29/29w4vote1.htm
On the ballot page, find:
Ballot No: ISO/IEC 14496-5:2001/FPDAM 6, Doc No: SC 29 N 5897
which is:
Information technology -- Coding of audio-visual objects -- Part 5: 
Reference software, AMENDMENT 6: Advanced Video Coding and High 
Efficiency Advanced Audio Coding reference software.
Notice the FPDAM status of this Amendment 
(http://www.itscj.ipsj.or.jp/eg/acronym.html).
This will lead you to:
http://www.itscj.ipsj.or.jp/sc29/open/29view/29n5897c.htm
On the bottom of this page you will find:

Since this Amendment is not public yet, could the availability of the 
source be a mistake from ISO?

p.s.
I have tried to compile the above mentioned ref code, however I did not 
succeed. I seems that a more recent Libisomedia.lib library is also 
needed. For example MP4TrackReaderGetNextAccessUnitWithPad(...) used in 
streamfile_mp4.c cannot be found in the Systems.zip ref. source from 
2001. Can someone from MPEG confirm this?
