As far as I'm aware, the BBC's audio estate runs at 48 KHz (well, except the Archers studio - and probably a handful of other studios - for legacy purposes). Looks like podcasts are still encoded to 44.1 KHz via iBroadcast (the MP3s' encoder tag indicates ffmpeg (currently Lavc57.24)). Except

Vangelis's mention of podcasts has reminded me of another comment I was going to make. A long time ago someone, it may have been Jim, took me to task for referring to a 44.1kHz sample rate. He said it must have been a very old file, because the BBC had standardised on a 48kHz sample rate.
