I would suggest that Pop's reliance on dynamic range compression was more
to
do with the "loudness wars" than limited bandwidth, especially since it
predates digital media.


A cigar for that man:-)

In pop music the public consider louder to be better.


Making it sound punchier on AM radio was the beginning of that.

Radio 1 started in 1967. When did that get its own FM service?

Louder is even more relevant now when most people
listen to music in their cars, or via earpods.

Also, the terms of reference are changing. People cosnsider
mp3 at 256Kb to be good, and 128 kb to be OK.

Many have an AV system in the living room, but I wonder
what percentage still have a proper listening room for music.
CD or vinyl?

Radio 1 took over the Radio 2 FM transmitter on weeknights from 22:00 to
midnight
and for live concerts on Saturday afternoons from the early seventies.
They were the only things worth listening to on Radio 1.

Isn't there a Radio Times archive where we can check these things?

How do you find the first 'time chunk' value when starting the process?


I just watched the http requests from within firefox using

Tools WebDeveloper Network

When pressing play, the first requests it does are

https://vs-dash-ww-rd-live.bbcfmt.hs.llnwd.net/al/lossless/client_manifest.mpd

and

https://vs-dash-ww-rd-live.bbcfmt.hs.llnwd.net/al/lossless/A1/IS.mp4

So maybe one of those contains the hint of the current block number?

Given the above, it should be possible to loop and fetch successive blocks
and cat them together into a file. Personally I'm *not* trying to play the
results 'live'. But if I can record enough of the stream I can start to
analyse it.

I dive in now and then to recorded Radio 1 things on BBC iplayer, the
rest is not any more for my ears. I listen to recorded music rather than
the radio.

Though in the eighties, me standing ready for hammering 'record/play' on
a C90 cassette, it was amusing to record the Sunday announcer handover
from Radio 2s 'sing something simple' to Radio 1 for the Top 40. It was
typically delivered with a kind amusing almost patronising warning for
them with fragile ears.

I think there is, but Radio 1 went full time FM somewhere in 1988. A
needless long time stalled by the same attitudes that were present a
long while ago when Radio 1 first launched.

Yes. That seems to give a 'recipy' but as yet I've not been able to work
out the required 'chunk number' to start from.

and


https://vs-dash-ww-rd-live.bbcfmt.hs.llnwd.net/al/lossless/A1/IS.mp4


My *guess* is that is a 'header' of some kind for the stream. But beyond
that guess I've not really been able to work out what it says.

I'll keep puzzling.

But surely Pick of the Pops pre-dated R1?

When R1 started in the London area, the transmitted quality was rather
better than average AM - if you had a suitable receiver. Until
international agreement limited the bandwidth on that frequency.

I have a tape somewhere with a simulcast - R1 AM on one track, and R2 FM
(mono) on the other, both from Quad tuners. With rather less difference
than you'd expect.

It seems that the Saturday evening Radio 1 'In Concert' was only on
VHF/FM from 1973.

I tried streaming the .mpd URL with VLC 3.0 nightly as it's supposed to
support DASH, it knew enough to get some metadata such as the name
"radio 3 lossless" from the manifest, but didn't play any audio,
sometimes it showed a timestamp into the thousands of
hours:minutes:seconds, other times it just showed 0:0:0

The DASH manifest is at:
https://vs-dash-ww-rd-live.bbcfmt.hs...t_manifest.mpd


It sounds pretty good with a decent soundcard feeding the hifi,
apart from the Windows bings and bongs.
And there was a ~105 second delay yesterday which made comparisons
interesting.

I wonder how the quality compares with DAB, Freeview, Freesat or iPlayer.
