The reason you couldn't find the link was that you need to click on the
left hand side - the grey "Now Playing" section. This is a separate frame
from the rest of the page and obviously gives different results to the right
hand side, when using Firefox/Iceweasel's View Page Info. The media tab
now shows the required link:
Append this to the BBC website address and use curl in a terminal window to
identify the direct
realaudio link, ie:
The BBC isn't deliberately hiding the link - some pages come with a "Open in
standalone player" link, others don't.
I would also reiterate the need for saving the stream in .wav format as
there is usually dross (news/announcements etc) at the beginning and end of
the file that needs deleting. This is best done on the lossless .wav file
rather than the lossy .mp3 - the latter is akin to re-editing a jpg file.
And the source audio isn't exactly CD quality to start with.
Audacity does a good job and offers many editing options and features.
To avoid having to remember the lengthy mplayer command line switches, I
generally record the stream then convert it, ie:
mplayer -dumpstream URL (this is .ra format and can be played with
mplayer -ao pcm stream.dump (this is .wav format and can be opened in
Incidently, others have already created direct links to many of the BBC
Funnily enough, your Friday Night is Music Night link is different in
each! Oh well, that's why we're using Linux - choice!
