The Library of Congress will showcase a range of treasures, technology and history from its recorded sound collection, the largest such audio collection in the world, in a daylong series of presentations and evening sound installations on Aug. 24.

Throughout the day, sound engineers and recording historians will present on a unique set of topics covering some of the earliest, most important and most unusual sounds in the Library’s holdings in the Whittall Pavilion and Room 119 of the Thomas Jefferson Building. Displays and presentations will include early experiments on cylinders through the many eras of radio broadcasting and the ongoing quest to expand the possibilities and achievements in recording. Visitors will hear an amazing range of sounds and the stories behind them.

Presentations in Whittall Pavilion:

10 a.m.: Binaural Stereo demonstration — In 1952, Emory Cook put stereo on vinyl for the first time, six years ahead of the major labels. It was expensive and cumbersome, requiring a two-headed tonearm to play separate channels pressed onto a disc, but it worked beautifully. Engineers Robin Wyatt and Tom Fine have recreated Cook’s system with a combination of original and modern gear and will play selections from Cook’s Binaural Stereo catalog and discuss his work and theirs.

11 a.m.: Quadraphonic demonstration — from the late 1960s to the late 1970s, four channel Quadraphonic mixes of music in every genre were the stuff of legend and heated debate. Sound engineer Rob Cristarella has curated a selection of the best and most unusual Quadraphonic selections of the era.

The Binaural and Quadraphonic demonstrations will be repeated throughout the day, alternating on the hour, with the last demonstration at 5 p.m.

6 and 7 p.m.: Surround sound history and demonstration — National Audio-Visual Conservation Center Record Lab Supervisor and Grammy winning sound engineer Rob Friedrich will discuss and demonstrate the history of multichannel sound mixing from the early days of stereo to today 5:1 surround mixes.
