something like this should work, assuming that you're in the directory
from which you wish to search:

$ find . -iname \*.aac | while read f; do ffmpeg -i "$f" -c copy
-bsf:a aac_adtstoasc "${f%.aac}".m4a; done

-- find finds files recursively, piping the list of files into 'while
read f' sets $f to each filename in turn.
