You are not writing a wav file, this is visible because you are not
including libavformat header files which would be necessary to
write a wav file.
I suspect you are writing an f32le file which should be playable with
something like:
$ ffplay -f f32le -ac 2 -ar 48k filename.
(Depending on the properties of the aac input file, the example is
for 48kHz stereo)

I thought that adts files cannot be read without libavformat but if
you see an output filesize>0, this is apparently not true.
