Why not flac?
because as others have pointed out, the raw data downloaded from the bbc
is aac. you can't improve the quality by removing compression,
I can't recall saying otherwise.
all this will do is occupy more space on your disk. All get_iplayer
does by default is re-package the (unchanged) aac data in an mp4 file.
Yes. For the avoidance of doubt I should add that I did know that. :-)
If you ask get_iplayer for mp3 then whether it was built to transcode
directly from the original aac or via flac would make no difference
whatsoever.
I think you've misunderstood the point of my question. Alas you've
also now removed the context so I have to add it back in the following..
If your player can't play the mp4a and you *need* to transcode the basic
choice is simple. You either:
A) transcode to some other 'lossy' format like mp3. This will be almost
certain to lose details.
or
B) transcoder to a loss-free format like flac (or lpcm wave). This can be
done with *no* loss of details.
You've now snipped the context which was that mp4a wasn't playable on the
player. That's the basis of the discussion.
So, because "leave it as mp4a" is taken not to be a useful option by the
conditions of the situation, the above choice may be unavoidable in the
circumstances. OTOH if you *can* play mp4a then obviously no transcoding is
necessary (except during replay).
So the point of my question was to find out if there was a reason why, *in
this situation where mp4a won't play*, you can't (or don't wish to) choose
flac. (B) allows the user to avoid more loss, not wave a wand to recover
what wasn't present in the mp4a.

If you have mp4a files which will not play on a chosen device then you
need to either find a device that will play them or save them and
transcode them into a format your existing device will play them.
Obviously if you transcode from one lossy format to another you will
alter the original to its detriment. As Jim says transcoding to flac
will result in a bigger file, but will not throw anything away.
Personal music players that will play anything are not hard to find.
My favorite is this

Expensive ? perhaps, depends what you want. One thing it does do is play
mp4a radio progs, I know I just tried it.
