[M4IF Technotes] mpeg-4 audio reference software

[marten.thielges student.uni-tuebingen.de]

Hello,
I have some trouble with the natural audio reference software, perhaps 
someone can help:
I have compiled the software (mp4auenc/mp4audec) for win32 using ms 
visual c++ 6.0 successfully (including afsp audio file format library 
and mp4 file format using libisomp4 - not libisomedia).
I can for example encode an audio file to mpeg-4 celp (the .mp4 file 
size seems appropriate), but the trouble lies in decoding the resulting 
.mp4 file.
mp4audec only returns "WARNING: error decoding audio file .... .mp4".
I also tried playing the resulting celp files in EnvivioTV (which 
supports mpeg-4 celp) and it failed as well.
Trying to decode the official audio conformance celp bitstreams with 
mp4audec.exe didn't work either :(
If someone has a working natural audio reference en-/decoder for win, I 
would be very thankful, if that person could send it to me via email.
Greets,
Marten Thielges
