Not audio per se but of equal historic value ... http://www.bbc.co.uk/news/entertainment-arts-34379547 An anonymous donor with links to John Logie Baird's home town has stepped in to ensure a historic recording of his first transmission of trans-Atlantic TV pictures will stay in Scotland. The 1927 footage, on a phonovision shellac disc, is the world's oldest surviving 78rpm piece of video. It features Logie Baird's ventriloquist dummy Stookie Bill, which he used when developing his invention. The recording will now be stored at Glasgow University.
