I don't think you'll be able to do much better than the equivalent of:
get_iplayer --get --type liveradio --mode flashaachigh 'BBC Radio 3'
plus the options particular to your setup. The flashaachigh mode gives
you the 320k stream. I don't think there is another source for the 320k
stream, so I'm not sure there is anything you can do with get_iplayer to
cure the dropouts.

That URL is not related to the media streams. If you filter the console
log by "mediaselector" you'll come up with something like:
for the old radio site or:
for the new radio site. The both carry the same information: the pieces
required to construct the call to the media server, JSON-formatted for
the web players. They point to the same media streams, at least for
Radio 3, which are the streams get_iplayer already uses. There is no
need to spelunk those URLs and construct those values since get_iplayer
already generates the same values. To compare for yourself, run:
get_iplayer --streaminfo --type liveradio 'BBC Radio 3'
