Until E! 2668 AUDIOCLAS, there was no method to automatically classify audio and musical sound effects. This EUREKA project has resulted in an objective sound-effect classification system that should provide a major boost to European film, video and audio production. The software system makes it possible to speed access to major sound-effect libraries and simplify synthesis of new or combined sound effects from the stored data. Audio DNA is used to identify sounds similar in nature, such as door slams. This classification and taxonomy of sounds is an innovative new approach that is already being used to provide web access to a range of commercial sound-effect libraries for both professional and domestic use in Europe.
The AUDIOCLAS project set out to establish an ‘audio DNA’ classification system, based on the decomposition of a sound effect into several thousand finite elements. With sound effects playing a key role in film, video and audio productions, many film companies and post-production houses rely on sound-effect libraries to avoid the expense of creating specific individual sound effects. And a growing number of home video makers are discovering the creative possibilities of using such libraries too. Close co-operation between a leading UK post-production facility and a Spanish university audiovisual studies department led to the development of a fully automated approach to sound categorisation. AUDIOCLAS resulted in a software-based tool that makes it possible to catalogue sounds quickly, logically and automatically. Indeed, sound effects held within the library have already been used in the two US-produced Shrek films. Searches can now be carried out using key words or by playing a sound and asking the system to find similar effects.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
