Comment:

 Duration is correct, as written by the encoder. We are just reading it
 wrong ON MONO files, and you are writeing mono here, Mediainfo is
 correctly reading them. I am closing this as duplicate of #5448.

 >But I am not sure its ok to have mp4 inside .aac file.

 The file you got must be renamed to mp4 as it is mp4. Also aac is just
 .adts, not aac. There is not such thing as ".aac".

 -f m4a is invalid. The way you do it is add out.m4a thag will
 automocatically add -brand m4a and mp4a and all the needed stuff in the
 header.
