WORKSHOP SESSIONS
Workshop W5
Small audio transducers, such as miniature microphones, earpieces,
and hearing aid transducers, are in an exciting phase of development.
New technologies, such as micro mechanics, are emerging,
but, on the other hand, improved manufacturing technologies and
materials have stretched down the limits for conventional transducers.
The limits of transducer technology and the promises of new
approaches will be discussed by a panel of experts from the industry
and the research community.
Workshop W6
Sound recordings are not only documents of historical, political
and cultural importance but also the outcome of the endeavours
and the artistry of the audio engineering profession. Over the last
decades we have witnessed an ever increasing interest for safeguarding
these documents and, thus, preserving the audio heritage for
posterity. Several problems, however, are associated with sound
archiving: The preservation issue is at the forefront as carriers are
not stable and newly upcoming recording systems see ever shorter
commercial life cycles. Another problem is re-recording, the technically
and ethically adequate transfer of historical sound carriers
onto new ones. A group of experts in the field will be invited to
critically discuss these issues including digital mass storage systems
which are just about to be introduced on a greater scale.
Workshop W7
The Workshop will examine the ways in which loudspeakers (and
microphones) pattern and the resulting sound system performance
will be discussed. The use of signal processing and other acoustic
techniques to form steerable arrays will be presented. Prediction
techniques and computer modelling methods will be also be discussed,
together with practical examples of arrays used in stadium and
concert sound systems through to teleconferencing and room acoustic
research / synthesis.
Workshop W8
Has the IFPI�s investigation into watermarking technologies revealed
satisfactory technological solutions? If it has, is there the
will within the industry to implement the application of copyright
protection information into DVDs or CDs (or even analogue
product?).
� Will the industry fund such implementation?
� Are studio producers happy with what might be new requirements
affecting their recordings?
Peter Filleul, from ESDA, the European Sound Directors Association,
chairs a panel of informed players, with contrary views, discussing
one of the most important issues facing the recording industry.
Workshop W9
It is well known that serious discrepancies exist between objective
acoustic measurements of parameters in sound production and
human perception related to it. The aim of this workshop is to
contribute to an extended knowledge of both current and upcoming
methods that can be expected to influence the application of
psychometrics in a broader range of psychoacoustic problems, such
as perception of loudspeaker distortion, product sound quality and
noise annoyance.
Workshop W10
MPEG-4 is the most recent member of the well known family of
ISO/MPEG coding standards. MPEG-4 provides an integrated set
of audio coders with a number of novel functionalities, such as
bitrate scalability and bandwidth scalability. It also supports new
concepts in audio coding systems, such as multi-signal composition
and interactive signal post-processing. The workshop will
present an overview of the MPEG-4 audio standard and discuss
how MPEG-4 can be used in specific audio applications. The
workshop will attempt to answer the question "What is MPEG-4
and what can I do with it?" There will be a number of demonstrations.
Workshop W11
For high-quality music and speech studios or small home-studios,
considering sound reproduction and good listening conditions,
some acoustical materials and construction are important. Descriptions
will be made in respect of microphone recording and
listening conditions. The absorbing and reflecting materials have to
fulfil different requirements which are sometimes related to desired
sound isolation between adjacent rooms. Reverberation times, early
and late arriving sounds, reflections and listening conditions will be
discussed for both small and large spaces.
