Hello,
It seems that R3 is broadcasting 320K aac streams for their evening
live
concerts. Can anyone guide me as to the correct --mode=?? switch to
secure those streams please?
Thank you.
Clive
Hi
It was mentioned in an email some months ago.
I can't find the email now, but this is the command to download the
320Kbps aac stream in an flv container:-
get_iplayer --get --type=liveradio
"http://www.bbc.co.uk/mediaselector/4/gtis/?server=cp60703.live.edgefcs.net&identifier=Special_Event1_UK@s6485&kind=akamai&application=live";
Thanks for the replay batguano - I can see this is to access the live
stream (which I have never tried but now I know how). What I was after
is the mode to d/l the file later. My default mode is --mode=flashaac
for R4 and R4Ex but that gets me 128K - is there a 320K equivalent
please?
Thanks.
Clive
Hi
I don't think that the Radio 3 'listen again' shows are available in
320Kbps format... but maybe I'm wrong.
See if someone else corrects me.
By the way, when using my previous command to download the live
320Kbps stream, it gives me better results if I include:-
--rtmp-liveradio-opts --live
in the command.
Like this:-
get_iplayer --get --type=liveradio --rtmp-liveradio-opts --live
"http://www.bbc.co.uk/mediaselector/4/gtis/?server=cp60703.live.edgefcs.net&identifier=Special_Event1_UK@s6485&kind=akamai&application=live";
Can you say a little more about what kind of better results you get when
you use this option?
Simon

Simon,
In general, any lossy encode at 320K will sound better than one at
128K. Less so for spoken word where the frequency range of spoken word
is relatively low. Much more so with orchestral music where the
frequency range from the lowest bass to the highest violin is so much
greater. On the 320K encode, the clipping and sibilance will be much
reduced. Now, this is all depending on ones own listening conditions
and the age of ones ears.
If you listen on small, cheap earphones while walking in the street or
travelling on public transport (as many of us do) then you may not
hear the difference much. If you play it back through a better pair of
headphones or speakers then the difference is immediately apparent. I
get much pleasure from orchestral music on a portable player, on cheap
headphones, with 128K or 192K encodes. When I plug that player into a
stereo amplifier and play back through a respectable pair of hi-fi
speakers, the music sounds constrained, restricted and 'boxy'. 320K
encodes reduce that effect greatly.
It seems that the 320K encodes can only be accessed from the live
stream and not from the listen again stream. This means recording live
rather than downloading later at ones own convenience.
I don't know how to tell the encode rate of a file from the file
itself. I have d/l an evening concert running to just under three
hours and had expected a file around 180MB. The file is actually over
250MB so that suggests the listen again encode is higher - can anyone
clarify this please?
Clive
Clive,
I agree about these benefits of 320k streams compared to 192k or 128k.
With 320k, I can really enjoy the music (on a good hi-fi system). With
192k or 128k, I can listen to it but I find it hard to really enjoy it.
I think the question in my previous post might not have been quite clear.
I was asking specifically about the benefits of using the "--live" option
of rtmpdump, and batguano has now explained this.
Simon
Simon,
Yes, I realised almost as soon as I hit the send button that I had
probably answered the wrong question. Many things in Windows respond to
the 'undo' button - email sending does not :(
