Not so easy ...

... Audiobook confidential: the art of reading aloud. (Hat tip, Paul Davis.)

The history of audio books begins in 1952, when Dylan Thomas was first persuaded – in the bar of the Chelsea Hotel – to record his poems.
He began the session with 'Do Not Go Gentle Into That Good Night’. But instead of a thin, quavery voice, Thomas gave of his deep, Welsh best. The microphone levels were duly adjusted.
Thomas continued to read, until the production team realised that the poems were only long enough for one side of an LP. To fill the other side, Thomas recorded a new work – A Child’s Christmas in Wales. The recording remains his everlasting testament.
