“ If I could record them and transmit them to the present age, they would constitute nothing more, nowadays, than dead sounds. They would be, in a word, sounds other than what they actually were, and from what their phonographic labels pretended they were – since it's in ourselves that the silence exists. It was while the sounds were still mysterious that it would have been really interesting to render the mystery palpable and transferable. ”
