To my surprise the above does work on windows/cygwin
I have been using faad -w aacfile | lame ... up to now - for
historical reasons - (SBR not implemented error) see
http://linuxcentre.net/bbc-iplayer-aac-radio-streams-now-available-using-get_iplayer
.
Anyway ...
I just did a rough experiment and faad seems to be about 2 times
slower than ffmpeg.

BTW I use lame --abr 56 for spoken word programs - the files come out
half as big as with -b 128.
