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

include over 100 papers, many technical tours and 15 challenging workshops,

providing a framework for professional fact-finding on the highest level.

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

“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

The City of ParisEach year, Paris has the privilege of welcoming manyvisitors from all over the world, eager to appreciateher splendors and curious to discover her secrets. Acity of many facets, Paris offers the richness of herhistoric, architectural and artistic heritage as well asthe diversity, charm and fascinating atmosphere of itsdifferent “quartiers”.

An economic, cultural, and scientific capital thatcombines bustling activity with quality of life, Parisoffers a full range of services. Visitors will enjoy a wideselection of restaurants and hotels, entertainment andcultural events, museums and monuments, and if theweather is mild enough, beautiful parks and gardens.

In terms of capacity, Paris has no difficulty in hostingevents that attract many thousands of visitors (e.g. thePope’s visit in 1997 and the soccer/football World Cupin 1998). But it is also a city with its own daily life andhabits and you will inevitably want to know more.

Travelling to Paris

Air TravelAn international meeting point, accessible fromvirtually any city in the world, Paris possesses twoairports: Charles de Gaulle (Roissy) to the north andOrly in the south.

Bus service from and to Charles de GaulleThe direct Air France Shuttle links the Charles deGaulle (Roissy) airport to the Palais des Congrès“door-to-door” in 45 minutes (shuttles every 20minutes).

OrlyvalThis automatic metro links Orly Airport to the RER(Regional Express Railway) in 10 minutes, from whereit is easy to reach the Palais des Congrès by the metro.

TrainVisitors from Austria, Belgium, Germany, Italy, TheNetherlands, Switzerland and the UK can enjoy thejourney by high-speed train. All lines offer specialrates for weekend tickets or single day return tickets.(Eurostar and Thalys allow visitors to attend theConvention for one day.)

Public TransportParis is proud of its very good public transport net-work: metro (subway), RER and buses. The Parisianmetro network consists of 16 lines, each identifiableby its number and final destination. The RER has 5lines and is linked to both the metro and some SNCFtrain lines. The entire public transport network isaccessible with a single pass for one, two or three daysor with a week pass. Sets of 10 tickets (ask for a“carnet”) can be also purchased, either in the metro/RER stations, or in the tobacconist shops (Tabacs).

TaxisThere are about 15 000 taxis in service in Paris. A taxifrom the Charles de Gaulle (Roissy) Airport or fromOrly to the Palais des Congrès will cost approximately300 FRF (45 EUR). From one of the 6 main stations(Gare de l’Est, du Nord, St Lazare, de Lyon, Mont-parnasse or Austerlitz), a taxi will charge between 100and 150 FRF (15 and 23 EUR). Taxis are not veryfamiliar with credit cards and cash is preferred forpayment.

Student Section ReportSaturday, February 19, 15:30 h – 16:30 h

The number of Student Sections in the AES isgrowing rapidly. Creating a Student Section is an ex-citing project which can greatly benefit students. It is,however, not an easy task when you’ve no idea whereto start. The aim of this meeting is to explain whatStudent Sections are, and how they can benefit youand your fellow students. We will then talk about thedifferent practical issues in creating a Section: Wheredo you get information from? How do you find outabout doing it in your country? How do budgetswork? What activities might you want to organisewithin a Section? In a student version of the Regionsand Sections meeting, each existing Section willreport on its main activities for the year, and raise anyproblems it has had, so that solutions can be workedout. Students wanting to create a section or simplyfind out about them are very welcome. EstablishedSections will also find a lot of interesting subjects arediscussed in this meeting. Please come with lots ofquestions!

Workshop W2Saturday, 19 February, 10:00 h – 12: 00 hACOUSTIC TREATMENT OF ASYMMETRICAL PLAYBACK ENVIRONMENTSWorkshop Chair: Vincent van Haaff, Consultant, USA

Environmental circumstances and the desired function of musicstudio control rooms may not always allow a strict symmetricalacoustic treatment about a central axis, while common sense wouldrequire such geometry. Many engineers and music composers havelittle choice but to make use of ever smaller spaces to do their work,and are forced to treat these spaces with the minimum loss of actualusable volume and floor space. What are some of the solutionsproposed to treat such axially challenging spaces? What constitutesan impossible situation?

Workshop W3Saturday, 19 February, 14:00 h – 16:30 hMPEG-4 VERSION 2 AUDIO – WHAT IS IT ABOUT?Workshop Chair: Jürgen Herre, Fraunhofer Institute for IntegratedCircuits (FhG-IIS A), Germany

MPEG-4 is the most recent member of the well-known family ofISO/MPEG coding standards, and provides an integrated set ofaudio coders with attractive capabilities, including bit-rate andbandwidth scalability. After the release of the MPEG-4 standard in1999, the new Version 2 Standards Addendum, to be published in2000, defines extended functionalities, such as low delay audiocoding, parametric audio coding, error resilience and spatialization.The workshop aims at answering the questions "what is MPEG-4v2 and what can I do with it?" and includes a number of demon-strations.

Workshop W4Saturday, 19 February, 14:00 h – 16:30 hDESIGN AND MODELING OF LINEAR ARRAY SOUNDSYSTEMS Workshop Chair: Paul D. Bauman, L-Acoustics, France

The recent renaissance of linear arrays for sound reinforcement willbe discussed, beginning with an historical overview and followed bya description of the theoretical principles and operating conceptsbehind a current example of a line array system. Techniques formodeling linear arrays will be discussed along with challenges invol-ved in simulation and measurement. It is hoped that a technicaltour of an installation at the Palais de Congrès will provide ademonstration of system performance and allow for the compari-son of simulated versus in-situ measurement results.

WORKSHOPS Workshop W5Sunday, 20 February, 09:00 h – 11:30 hMULTICHANNEL SOUND IN THE CINEMAWorkshop Chair: Graham Edmondson, Dolby Laboratories, UK

Multichannel sound has revolutionized an audience's enjoyment ofthe motion picture experience. In this workshop, representatives ofdifferent film industry sectors will be presenting and discussing thefilm multichannel sound production and post production proce-dure. Special emphasis will be given to the changes brought aboutby digital multichannel sound, which is now used on the majorityof feature films.

Workshop W6Sunday, 20 February, 14:00 h – 16:30 hACTIVE REVERBERATION SYSTEMS FOR AUDITORIAWorkshop Chair: Mendel Kleiner, Chalmers University ofTechnology, Sweden

Active reverberation systems for auditoria have been commerciallyavailable for more than 30 years. Considerable research effort hasbeen invested, and has resulted in many competing technologicallydifferent systems. Although some of these systems are quite effi-cient, relatively few active reverberation systems are in actual use,especially in Europe. After a brief overview of the reasoning andtechnology behind various active reverberation systems, this works-hop will debate the reasons (economical, acoustical, scenographic,psychological) for their success or failure, and look for possible futu-re systems and technologies.

Workshop W7Sunday, 20 February, 14:00 h –16:30 hTHE BINAURAL REPRODUCTION OF MULTICHANNEL SOUNDWorkshop Chair: Günther Theile, IRT, Germany

There are now 5.1 sound channels. However, suitable 5.1 loud-speaker reproduction is not always practical or desired. In Part 1 ofthe workshop we will discuss auralization methods aiming atadequate headphone listening. Particular aspects will be: model-based versus data based systems, relevancy and feasibility of headt-racking, complexity levels versus scope of applications. Part 2 willfocus on multimedia applications, and discuss possibilities andlimits of virtual surround reproduction using two nearfield louds-peakers.

Workshop W8Monday, 21 February, 09:00 h – 11:30 h

Workshop W9Monday, 21 February, 09:00 h – 11:30 hCOMPARATIVE STUDY OF 8 MULTICHANNEL SOUND RECORDING ARRAYS OF THE 40 VOICES “MOTET” BY TALLIS AT THE PARIS NATIONAL CONSERVATORY OF MUSIC Workshop Chair: Christian Hugonnet, France

The panel will consist of a representative from each of the authorsor the groups participating in this recording. The aim of this works-hop is to compare 8 different microphone arrays according to 5.1reproduction format as recommended by ITU-R BS 775-1. Thiscomparative study is based upon the simultaneous recording in thesame acoustical conditions of the same musical work: the 40 voicesmotet “Spem in alium” by Thomas Tallis, interpreted by “LeMadrigal de Paris” in the Paris National Conservatory of Music on11th November 1999. The circular placement of the vocal soundsource around the audience will be of special interest in establishingthe coherence of the reproduced sound field. The different systemswill be discussed by their authors and the debate will include someresults from the surround demonstration of the "motet".

Workshop W10Monday, 21 February, 14:00 h – 16:30 hEVALUATION OF INTERMEDIATE AUDIO QUALITYWorkshop Chair: Thomas Sporer, Fraunhofer Institute forIntegrated Circuits (FhG-IIS), Germany

Subjective and objective methods for the evaluation of the percei-ved audio quality are well established both for high-quality audiosignals and speech quality levels. Low bit-rate coding enables thetransport of audio signals on the Internet. The obtained quality ismuch better than the usual “telephone quality” but far from trans-parent. In this range, the classical measures of quality evaluationsare no longer applicable. In this workshop the special problems ofthe evaluation of this so-called intermediate audio quality arediscussed. Experts from EBU and ITU-R working groups will alsogive a preview on an up-coming recommendation for listening testsand insights to the activities concerning objective evaluation.

Workshop W11Monday, 21 February, 14:00 h – 16:30 hLOUDSPEAKER ARRAY RADIATED FIELDWorkshop Chair: François Deffarges, ORPHEO, France

This workshop intends to draw a panorama of today's situation andtomorrow's expectations in the control of the radiated field of loud-speaker arrays. Control of the radiated field of a loudspeaker systemis clearly a determinant factor in the success of a sound systemdesign. Arrays assembled with the traditional sound reinforcementsystems do not give satisfactory results as there is so much acousti-cal interference that the response is totally dependant on thelistening position, and the resulting homogeneity is poor. Further-more the concept of directivity is irrelevant because one is unable tocharacterise the radiated field. Over the last few years, new conceptsin arrays have emerged: line sources, plane sources, parabolic sour-ces,… and day-to-day progress in DSP technology is introducingnew methods that can be used to control the radiated field of anarray.

Workshop W12Tuesday, 22 February, 09:00 h – 11:30 hSHOULD NETWORKS HANDLE AUDIO?Workshop Chair: Mark Yonge, Solid State Logic, UK

As digital audio techniques become dominant, computers becomefaster and network bandwidths increase, traditional methods ofmoving audio from place to place must be re-assessed. Why wouldyou continue to use tape? This workshop explores the future ofmoving audio between professional production processes and willlook at some alternatives.

Workshop W13Tuesday 22 February, 09:00 h – 11:30 hSPEECH INTELLIGIBILITY THROUGH PUBLICADDRESS AND TELECONFERENCING SYSTEMSWorkshop Chair: Peter Mapp, Consultant, UK

This workshop will focus on the influence of loudspeaker and roomacoustic characteristics on the perceived intelligibility of voice.Aspects such as loudspeaker directivity, frequency response anddistortion will be discussed, together with the effects of S/N andD/R ratios and echo perception. Methods of measurement andprediction will also be presented after an illustrated introductorytalk presenting current knowledge. The discussion should behelpful to loudspeaker manufacturers, and to PA and sound rein-forcement system designers.

Workshop W14Tuesday, 22 February, 14:00 h – 16:30 hRADIO@INTERNET: A PROGRESS WITH SEVEN-LEAGUE BOOTS? Workshop Chair: Gerhard Stoll, Institut für Rundfunktechnik,Germany

The Internet’s impact on broadcasters has changed from its initialposition as a site for posting broadcasting information to its emer-gence as a valuable additional medium to reach new customersthrough streaming audio and new interactive concepts using pushand pull technologies. Audio, which is still using only a small partof the capacity of the Internet, has become a window to the WorldWide Web – audio information delivered via IP, downloading oronline streaming. Several software companies are developing thenecessary tools to distribute audio and video on the Internet withthe goal to develop the Web into a new mass medium, compared totraditional audio or video broadcasting.

Workshop W15Tuesday, 22 February, 14:00 h – 16:30 hUSE OF CAD TOOLS IN ROOM ACOUSTICS ANDSOUND REINFORCEMENT SYSTEM DESIGNWorkshop Chair: Jacques Martin, CSTB, Grenoble, France

A lot of effort has gone into developing CAD tools for the acousticdesign of auditoria and sound reinforcement systems. Severalpowerful systems are now on the market (some with auralization),and results issued from these software programs can often be seenon technical reports. This workshop will address the followingquestions: What are these tools actually used for by acoustic consul-tants and other professionals? What are their true technical capa-bilities and limitations? How do they combine with other designmethods? What is their commercial interest for convincing clients? How could they be improved? Participants will include acousticconsultants, sound system engineers, and researchers.
