iPlayer radio bitrates

I'm not a computer expert. But I think you may have missed the point.

The website in question is offering access to the BBC's real, actual stream. It's offering you the .WAV stream that underlies all of the BBC's streaming content.

Go back to the site, read again what it explains there, then download an iplayer file, giving it the extension .WAV (instead of the default .FLV extension allocated to streams by the BBC), and you'll find the actual 1500 kbps uncompressed stream downloading. Only .mp2 will stream at 384 kbps, although .ts will stream at 320 kbps. The .mp3 or .m4a streams run at only 128 kbps.

MP2 was designed for high bitrates, so it in fact performs better than other options at 384 kbps, whereas it performs relatively poorly at 80 kbps (the BBC use mp2 as a DAB stream at 80 kbps).

Interesting --

The brand new Dash AAC streams and the existing HLS AAC streams are both 320kbps. I'd certainly take a 320kbps AAC file over a 384kbps MP2 file, as the quality should be better due to improvements in the more modern codec. In fact, MP3 dropped supported for 384kbps for much the same reason -- a 320kbps MP3 will sound superior to a 384kbps MP2 in most cases.

Do you happen to know the underlying codec used in the MPEG or TS files? I suspect that it's the same 384kbps MP2 data, but I haven't grabbed the files to double check.

Get_iPlayer is sometimes useful, but for the full bitrate stream - the 384 kbps stream - you need other solutions.

Here is a very straightforward way to get that stream with radio downloads from BBC iPlayer -

I'm reviving a dead topic!

Remember when I said that the iPlayer serves a better radio bitrate to listeners in the UK, and you all laughed?

Well, okay, very politely corrected me.

It turns out I was right!

Although I'm not so much telling you this to gloat, and more as helpful information for those who download shows from the iPlayer. Anyway, there's a guide to formats for get_iplayer here. I think part of the confusion may have been that you need a recent build of get_iplayer to grab the 320kbps stream:
