Jim,

Perhaps you could use your vast influence at the Beeb [:-)] so that this
"experiment" continues after the The Last Night!

TBH at present I've not decided if for me 320k gives a satisfactory
trade-off between reliability of stream connection and quality. Dunno about
you, but so far, each time I've tried the current experimental stream I get
drop outs on average about once or twice an hour (about 1 sec lost each
time) which rather disrupts listening to a long piece of music. Wheras at
128k or 192k I almost never get such dropouts.

Slainte,

Jim

Steve the digitalradiotech fella has just sent his round his email list,
fyi etc:

***
The BBC has launched an "experimental" 320 kbps AAC Internet stream
carrying the Proms. The stream will be available until the Last Night of
the Proms on Saturday 11th September, and the BBC would like people to
listen to the stream while the Proms are on, then to provide feedback by
filling in a short online questionnaire.

As it is an extreme rarity for the BBC to care about the audio quality
it delivers on digital radio, let alone experiment with a bit rate as
high as 320 kbps, I would urge as many of you as possible to have a
listen to this stream and to fill in the online questionnaire afterwards.

The 320 kbps AAC stream can be found he

http://www.bbc.co.uk/proms/2010/audioexperiment/

The online questionnaire is he

http://ecustomeropinions.com/survey/...?sid=471224792

And a BBC Internet blog about the "extra high quality audio experiment"
can be found he

Thanks. FWIW I'd already had the same info from the BBC directly - ahem
minus, of course, Steve's added opinions. :-) IIUC the survey and blog
should also be findable from the URL I posted when I started this thread.

I'd certainly encourage people to try it while they can and report their
experience.

Slainte,

Jim

How is your broadband connection though? I pay a little extra for the
professional option from Plusnet. It guarantees maximum line bandwidth
on all ports and services. I was downloading the latest TomTom Western
Europe map the other day, and had the network monitor running to see
how it was going. Here is what the monitor made of most of the
transfer.

Rock solid 16Mb/sec and no dropouts. That is about 1GByte on that
display. That makes light work of 320kb/sec.

That's all very well if you live close enough to the exchange. If, OTOH, you
have 4km of overhead cable between you and the exchange (as I do) 16Mb/s is
the stuff of fantasy. Just 10% of that would be a dream!

You mean you wont move house just to increase your broadband speed?
What kind of commitment is that?

Fast enough that I can normally watch the *TV* iPlayer without problems
if wish.

For reference I just checked using the BBC iplayer diagnostic and for both
my laptop and shuttle this gave 2400 kbps for download speed and 2200 for
streaming. I'd agree that isn't very fast. But it should be ample for
320k *provided* the connection streams reliably.

I also use 256/320 from elsewhere at times. The problem can be with
occasional brief delays. My guess is that this is simply a machine
somewhere along the way being temporarily otherwise occupied or some
packets going AWOL. Hence I suspect this is a matter of the levels of
buffering/retries/requests not being quite adequate.

Slainte,

Jim
