Listening to the BBC Radio 2 Electric Proms in HD Sound
Tim Davie, BBC Director of Audio & Music, announced on 18th October that the BBC would make some of the BBC's online radio output available in an extra high quality format that we're calling 'HD Sound'. Listeners in the UK can enjoy the BBC Radio 2 Electric Proms in HD Sound during the concerts broadcast from the 28th to 30th October.
To listen in HD Sound you will need to follow the link from the Electric Proms web page. There you'll also find a link to a survey for you to tell us what you think of the sound and how well it performs. Please do complete the survey - this is the first Radio 2 concert using HD Sound and we need to know how well it works for you.
HD Sound is a very high quality audio feed delivered over the internet. It uses a higher bit rate to deliver the sound, 320kb/s compared with the normal 128kb/s for Radio 2, giving much more detail in the audio. HD Sound also has a much wider dynamic range; that is, the change in loudness between the quiet and loud parts of a concert will be much greater than we normally broadcast. The wider dynamic range will give you an experience much more like the one you would hear if you were at the concert. The greater change in loudness may require listeners in noisy places or those who want the music on "in the background" to turn the volume up to hear the quiet parts and then turn it down again for the louder parts of the music, if you don't want to do this you may prefer the normal sound available through iPlayer, radio and TV.
The Electric Proms will only be available in HD Sound through the special web page, and only within the United Kingdom. We will move HD Sound into the iPlayer as soon as we are sure it will work reliably for everyone, in the meantime anyone having trouble with the HD Sound player can use the iPlayer to receive the usual high quality sound. We will make the Electric Proms concerts available on-demand (for 'listen again') in HD Sound too, so you can listen to the first of the concerts, featuring Elton John, on the Electric Proms web site now. The live concerts will only be available in HD Sound through the special Electric Proms web pages, not in the iPlayer.
