I don't know if this will work with Chrome on Linux, though. At present I
use FireFox on fairly old distros and feed the output out via USB. Fear I'd
have to change a lot of that for it to work! Anyone using a system that
might work who can comment? FWIW I'm asking a couple of people at the BBC
about this, but they all tend to use Windows/Macs so probably can't help
with anything Linux specific.

As often, you quote in your sig making replying a PITA.

The answer depends on which "we" you refer to, or if you are using it in
the "Royal we" sense.

Some people may prefer listening to music in surround sound. e.g. to get
the concert hall reverb and atmosphere around them. I can see the point of
this for items like Proms broadcasts, etc.

Others won't be very interested.

Your choice may not be the same as others. But the aim is choice.

MPEG-DASH, I see. I get that it's an advance in technology, gives better
load balance on the servers, is less likely to cause dropouts, and handles
forward and backward jumps well. Of course, it does mean that you need the
latest software to play it, but if you've got some media playing device
that's not going to get another firmware update then hard luck.

The first I knew about DASH was when I was looking a physics lecture in a
series that I'd been following via my TV's Youtube player and noticed that
I could no longer clearly see what the lecturer was writing on the board. I
then tried the Youtube-plugin for the Raspberry-Pi's "Raspbmc" media-player
and found exactly the same problem. A bit of research informed me that
Youtube were now supplying the 480p-resolution videos in DASH format only,
and anything that couldn't handle DASH would drop down to 360p which was
still supplied in the old MPEG format. (Likewise 1080p videos would drop
to 720p.) This forced me to find out how to download Youtube DASH videos
so that I could convert them to a format that I could use, even though I
would prefer to stream them. Luckily it only involves downloading the
separate audio and video streams and stitching them together, but not fully
recoding them. This guy explains how:

Doesn't help me at the moment as I can't view it on this machine. However a
written explanation may be of more help to me anyway.

So might it be possible for us to fetch and save the BBC stream, then
process it to hear and analyse? That would actually be useful for me as I
want to examine the data stream and examine it for any problems. And I
don't really have any systems that play surround.

The tool used in the video that I mentioned is a front-end for the
"youtube-dl" command-line app, which can actually download from hundreds of
sites, and which works fine for videos so I've not investigated further. I
understand that the server slices up the audio, (and video in the case of
the video sites) and provides them via the "Media Source" API. The client
app requests the chunks (using AJAX requests?) and stitches them together.
So yes, it's possible but you'd need to research the apps, and if nothing
is suitable, look at grabbing the media chunks with Javascript maybe.

If you want to read some opinions from people who know their
music/sound/venues there are quite a few posts on the subject today on

https://mail.music.vt.edu/mailman/listinfo/sursound

It's normally quite low traffic - but if you don't want to sign up just
to read their own archive, I think there are public ones of it to be found.
