Acoustical Testing of Rooftile’s Quality
Industrial production is always closely connected to quality
control. Already in the production process it has to be guaranteed
that only best quality products leave the factory. Until now,
the common test scenarios for the quality of rooftiles involved
a sound check which is usually done by sorters. The Fraunhofer
IDMT developed a method for the automated acoustical testing
of roofing tile’s quality.

Activation of Cochlea Implants
Millions of people are handicapped by severe hearing loss
or deafness. Electronic inner ear prostheses, so called cochlea
implants, which substitute the function of the damaged inner
ear, can improve the quality of life significantly. Thereby,
the activation of the implants plays a decisive role for speech
comprehension. The newly developed simulation software, based
on a neurophysiological approach, achieves a better activation
of electrodes for cochlea implants.

AudioID
Locating and identifying audio content has become a key issue
in today's music distribution business and database administration.
The AudioID system is a recognition technology that detects
audio material automatically and provides content information
like song title, interpret etc.

Audio Source Localization
Within the project audio source localization the researchers
focus on the ability of the human hearing concerning the identification
and localization of sound sources. By means of modern technology
the properties of the human hearing are simulated in order
to apply them to new applications.

Beat Tracking
The synchronization of multimedia content to musical signals
often has real-time requirements. Thereby, the determination
of the temporal positions of beats in a piece of music is
of major importance. For this purpose, Fraunhofer IDMT developed
the so called Beat Tracking for the synchronization of any
audio and video software via a MIDI interface.

Within the EU-project Carrouso, European members from industry,
research und universities merged their expertise in the field
of advanced audio, multimedia and telecommunication. The key
object of the project was to provide a new technology that
enables the transfer of a sound field – in combination with
visual data – to any remote located space.

Educational Media
Merging of recent findings in the areas of information and
communications technology, web-based learning, cognition and
user-centred system development efficiently supports online
learning. Simultaneously, this integration can powerfully
increase the learner's motivation and improve human learning.
Enhanced concepts of use and interaction are the basis for
success due to addressing the aspects of human recognition,
user acceptance and useful application.

Flat Panel Loudspeakers
According to the "bending waves principle", the
researchers at Fraunhofer develop flat panel loudspeakers
which are just a few centimetres thick. Thus, they can be
integrated in pieces of furniture, in walls or in pictures
in living or conference rooms, creating a natural and realistic
sound.

Freebies
The music fans of today buy their albums less and less in
music stores – they rather simply recommend music to each
other and exchange files or CDs. This exchange of music happens
unfortunately mostly illegal. With the development of Freebies,
online sales could be increased and negative effects on the
music industry could be restricted.

Spatial Mixing Desk
Professional audio technology requires the correct acoustic
perspective of sound perception. This calls for a sound system
which enables a perfect directional hearing and distance perception
for the listener. In close collaboration with Bregenz Festival
and Lawo AG, Fraunhofer Institute for Digital Media Technology
developed a new spatial audio mixing desk. The system was
optimized for both static and dynamic sound sources and represents
the state-of-the-art of directional hearing.

conferencing systems are still expensive and quite complicated
to handle. Using motor driven webcams with PC based video
conferencing software is a low-price and easy-to-use solution.
Researchers at the Fraunhofer IDMT developed a voice controlled
camera solution for video conferencing via PC localizing and
tracking speakers in the surrounding environment.
