Bother! Only yesterday I bought a ticket for a concert and now I find
that I can stay at home and listen to it in very hi-fi.

Is there any way to record the stream?

Virtual recorder maybe?

There probably will be various ways to do so. In fact, that's what I'm
trying to sort out at tghe moment! :-) The snag for me is that I want to
record what *arrives*. Not what may get though a browser and any OS
'mixers'. etc.

It just seems to fetch a sequence of ~200kB files

with each one containing 3-4 seconds of audio, whether or not you could
use wget/curl/etc to grab and concatenate the segments, then play the
result with vlc or some other ffmpeg based app, I don't know ...

How do you find the first 'time chunk' value when starting the process?

Given the above, it should be possible to loop and fetch successive blocks
and cat them together into a file. Personally I'm *not* trying to play the
results 'live'. But if I can record enough of the stream I can start to
analyse it.

I just watched the http requests from within firefox using

Tools WebDeveloper Network

When pressing play, the first requests it does are

https://vs-dash-ww-rd-live.bbcfmt.hs.llnwd.net/al/lossless/client_manifest.mpd

and

https://vs-dash-ww-rd-live.bbcfmt.hs.llnwd.net/al/lossless/A1/IS.mp4

So maybe one of those contains the hint of the current block number?

They recommend a broadband connection 2 milibits per second.

Which is why I thought it was an April fool.
Also although flac is a compressed medium, its not a real time thing, its a
bit like zip. this is why very few players can play it like Ipods etc.

I also know from experience that any attempt to send such files over a lossy
compression won't work.

It sounds pretty good with a decent soundcard feeding the hifi,
apart from the Windows bings and bongs.
And there was a ~105 second delay yesterday which made comparisons
interesting.

I wonder how the quality compares with DAB, Freeview, Freesat or iPlayer.

I've now managed to build a version of ffmpeg that lets me fetch and record
the R3 flac stream. The process of making this is a bit geeky at present,
but if anyone is interested it is being discussed on uk.comp.os.linux.

Managed to capture the programs that were on R3 from 12 - 2 today. But so
far 'tests' have just been: "Yes, it is flac. Yes, I can hear it." But
quite promising as a start. :-)
