Comment (by heleppkes):

 If you want accurate duration and bitrate information, then store it in
 mp4/m4a, not raw .aac - or encode as CBR.

 Raw aac files don't have any way to store duration or bitrate, and if you
 encode it as Variable-Bitrate (VBR), there is no good way to accurately
 determine this information, and all it can do is  guess.
