That's smart Marshall. :-)

(I didn't know that Radio 3 HD 320k was now available using a pls feed).

Your commmand can be simplified a little:-
mplayer 'http://www.bbc.co.uk/radio/listen/live/r3_aaclca.pls' -dumpstream -dumpfile r3.aac

Then wrap it in m4a:-
ffmpeg -i r3.aac -acodec copy -absf aac_adtstoasc r3.m4a

I think using the "pls" feed with mPlayer will be more reliable than using the "mediaselector/special_event" feed with get_iplayer. ;-)
