Here are relevant details (copied from my posts in the other thread):
Tonight [ 15/16 January] I have stumbled across an extremely high quality source of internet radio. It's provided by BBC 3. This post (from http://www.harbeth.c...14250#post14250 ) provides details:
BBC Radio 3, the British Broadcasting Corporation's 24 hour classical music service, is now available as a continuous 320kb AAC high-quality stream. This is as close to the ex-studio feed as you can get.
As I have the free VLC Media Player installed on my W7 PC, clicking this link starts the streamed audio decoder and recognises the format.
BBC Radio 3 stream is here: http://www.bbc.co.uk...e/r3_aaclca.pls
VLC player, if necessary is available here: http://www.videolan.org/vlc/
This really is as good as it gets on-line. If you listen closely to the presenter's voices, you can clearly hear the whirr of equipment and the acoustic of the studio from which they are talking - and the characteristics of their microphones. I assume that there is no equalisation or signal processing, and that the 15kHz low pass filter that applies to all (BBC) broadcasting has been applied but this can easily be checked with a spectral analysis plot.[/indent][indent=1]

This evening I have been listening to the stream. VLC player confirms a bitrate of 320kbps AAC. (The sample rate is 44.1kHz..) That bitrate should be high enough for AAC to be indistinguishable from CD sound.
Listening with a high quality headphone amplifier and high quality headphones, I found the sound superb.
To the British Broadcasting Corporation: a big thank you.

(Not all of the HD material shown will stream to Australia. Some is blocked.)
WARNING. If connected for long periods, the bandwidth consumed may become significant, depending on your internet plan. 320kbps = 144MB per hour ≈ 3.5GB per day
