The input file is here:
>>> The problem seems easy to reproduce, I downloaded
>>> >from http://samples.mplayerhq.hu/A-codecs/AC3-samples/
>>> the file Broadway-5.1-48khz-448kbit.ac3

The output file is easily reproduceable by

ffmpeg -i Broadway-5.1-48khz-448kbit.ac3 -ab 384 broad384.ac3

do you want me to upload the result broad384.ac3?

Regards,
V?ctor
