Not to be confused with HD Radio, the BBC is to launch a new enhanced radio listening service called HD Sound.
BBC Radio 3 will be the first station to benefit from the facility, which was announced by BBC Director of Audio and Music Tim Davie.
From the beginning of December, the BBC will offer "HD Sound" on the Radio 3 website.
Writing on his blog this morning, Tim said: "We will quickly assess the performance of this before making the higher quality stream available on iPlayer and the proposed radio industry player. Radio 3 listeners will get the benefit of the highest quality broadcast available anywhere. Interestingly, it was Radio 3 that led the charge in 1971 as radio moved to stereo, and once again it is excellent to see it at the forefront of innovation.
"As with Stereo, I would expect to see further roll-outs of HD Sound over time and we have already announced that we will be trialling it for Radio 2 at the Electric Proms. I am expecting that the performances by Elton John,Robert Plant and Neil Diamond will all be available."
Tim Davie will be appearing at the Radio Festival tomorrow in the Meet the Bosses section from 9:15am.
