Only 13th June but this could kick ass improvements in the uk
elsewhere!

I look forward to listen again shows at over 100 bitrate??????? In
near CD Stereo!!!!

I remember they were going to increase to 128k.
Is that 128k aac or are they going to use some other codec.

This player may hide the bit rate. Is this done deliberately? Like
all the american ones?

There's an application called NetMeter, which you can use to measure
the bit rates - e.g. zero the totals for the amount downloaded, then
start playing an Internet radio stream and let it play for a few
minutes (without downloading anything else at the same time), then
divide the total number of bits downloaded (number of bits = number of
bytes x 8) by the duration which gives you the bit rate. I'm not sure
whether the amount downloaded includes TCP/IP packet headers or not,
but headers are meant to account for as low a percentage of data
downloaded as possible to be efficient, so I doubt it would make much
of a difference - I might check that one day, actually.

The adoption of DAB was the most incompetent technical
decision ever made in the history of UK broadcasting:

I looked on Google and at ISpreview website the application is
£10...is this below any good? Thanks for your assistance

Netmeter was free as recently as last April when I updated mine, but
today the site requires registration but implies it is still free -
there is a Donate button.

It's only a 600KB .exe. Ask someone to send it to you. :-)

I now have it installed http://www.hootech.com/NetMeter/ Now to
grasp how to get bit rates that stations hide in America like cbs

I have a radio station playing through Winamp that is 128 kbits
according to shoutcast playing last 10 mins and on net meter it has
max 916.5kbs in red down 258.6kbps 281.9kbps 281.9kbps then in green
6.1kbps and 9.2kbps.

So how do I get to the bit rate of 128k ???????

Right-click on the NetMeter window, select Totals. On the Totals tab,
click Reset, which sets the Data downloaded since xxxx to zero and
changes xxxx to the current date and time.

Start playing the Internet radio station and time how long it's
playing for.
Stop playing the Internet radio station.

Multiply the value for KB downloaded by 8192 (because 1 KB = 8192
bits), then divide by the duration that the radio station was playing
for to give the bit rate.

So in red downloaded I am getting 34.5 Down KB/sec...playing for 7
mins
so is that 34.5 times 8192 divided by 7?

The values listed on the graph are the maximum download speeds.

No, you've got that all Pete Tong.

The bit rate is calculated by:

bit rate = number of bits / time in seconds

You're dividing a bit rate by a time in minutes, which is completely
wrong. You need to first get the number of bits received, not the bit
rate, and you need to have the time in seconds, not in minutes.
