Founded in the United States in 1948, the AES is the only professional society devoted exclusively to audio technology. It is an international organisation that serves audio engineers, creative artists, scientists and students worldwide by promoting advances in audio and disseminating new knowledge and research. The site offers a wealth of resources, most of which are available to paying members only. They include: Tutorial presentations from conferences and conventions, Oral Histories, and an E-Library which documents the progression of audio research from 1953 to the present day. The UK section of the AES offers some lectures via their YouTube Channel, and reports and recordings of past meetings, which are organised chronologically and go back to 2008.
