108TH AES CONVENTION PALAIS DES CONGRÈS PARIS, FRANCE 2000 FEBRUARY 19-22 PRELIMINARY PROGRAM CHAIRMAN’S WELCOME

Dear Attendants,

Only a few weeks to go until the 108th AES Convention opens its doors to pro- audio specialists from around the world. With an extensive Convention Program and Equipment Exhibition, the first AES event of the new millennium will present technologies and ideas, both established and visionary. This Paris Convention is the ideal location to help guide you through the latest trends and technological changes. The turn of the millennium heralds groundbreaking innovations in the pro-audio sector. Multichannel audio, for example, seems as important a breakthrough as was the introduction of stereo. After a long period of technical fine-tuning, we are faced with the basic aesthetic and artistic questions, and once again the AES is there to help you make the right choices. For over 50 years, the AES and its Conventions have been the link within the international audio community: a forum for exchange of new ideas. At the dawn of the new millennium and the age of globalisation, the role of the AES will be more important than ever before. As Chairman, and on behalf of the 108th Convention Committee, I am very pleased to announce an exhaustive Convention Program: 19 paper sessions that To participate, please include over 100 papers, many technical tours and 15 challenging workshops, return the advance registration form by providing a framework for professional fact-finding on the highest level. February 11, 2000 The student activities too will be more intense than ever before, thus contributing to the AES Convention’s recognition throughout the world as a major platform for future generations of audio engineers. Special events of both a technical and artistic nature will punctuate this Paris Convention and include a concert by Graham Blyth on the world-famous Model of the newly renovated Palais des Congrès “Cavaillé-Coll” organ of the Madeleine Church. Come to Paris to celebrate the turning of this important page in History! Yours,

Daniel Zalay 108th AES Convention Chairman
