For the AAC part:

GStreamer's default AAC decoder uses libfaad.
I could not see anything wrong after a first check of the plugin, though
outputting its output to a raw file shows the first thousand or so samples to
be missing. So I downloaded libfaad (1), and the same issue happens with its
command line tool - the first few samples are cut off.
Manually selecting ffdec_aac in place of faad in the same gst pipeline gets it
right, noise is head at both ends. So it's a bug in libfaad.
