Flashaudio no longer available for Radio 4?

for what its worth,
I once messed around with capturing some AAC streams
I had troubles getting them to work with my iPod (2nd gen Touch I think) until I did this:
mp4box -add input.aac:mpeg4 -sbr -ipod output.m4a
The main flag required for iP*d compatibility seemed to have been specifiying the :mpeg4
(not just the obvious -ipod)
Maybe give that a try and see if it helps!!
NB you may not need the -sbr flag, depends if the stream is HE-AAC/AAC+ (AAC-LC + SBR), or HE-AACv2 (AAC-LC + SBR + PS)
...even if you don't need the flag, I don't remember if it even makes a difference...
mp4box should be available round and about, including here:

> It's possible to convert the BBC aac files to nero m4a files like this:-
> ffmpeg -i filename.aac -f wav - | neroAacEnc -ignorelength -if - -of output.m4a
> But it's pointless, may as well just convert to mp3 with ffmpeg like this:-
> ffmpeg -i filename.aac -acodec libmp3lame -ab 128k output.mp3
> And to encode much quicker pipe to GOGO-no-coda with ffmpeg like this:-
> ffmpeg -i filename.aac -f wav - | gogo -b 128 -q 0 stdin output.mp3
> GOGO-no-coda cuts the encode time to around a third.
> For example, to convert a 2 hour show takes me approx 12 minutes using ffmpeg and libmp3lame.
> With gogo it takes approx 4 minutes.
