ADTS header data is invalid sometimes? Why?
Hello all,

I hope someone can direct me on the right path before I put a lot of time and effort on this.  I'm currently trying to parse an AAC+ frame to get information such as number of channels and sample frequency.  So it seems that we can simply get this information from the ADTS header but most of the time this information is inaccurate.

So the question is:
-Why is this data inaccurate? What is the meaning of the ADTS header channel and sample freq?
-Should I parse further down the frame to get this information? Would that be accurate information?

Thanks for the help!
