Fraunhofer Institute for Digital Media Technology IDMT

Excellent applied research for your success

Monitoring of industrial manufacturing processes, traffic monitoring or identifying manipulations in audio data - at the headquarters in Ilmenau, Thuringia, everything revolves around the safe and efficient AI-based recognition and classification of audio and video data. Another focus is the development of audio technologies for virtual acoustic product experiences as well as customized solutions for the production and reproduction of authentic and spatial sound experiences for the professional audio and entertainment sectors. We serve the current trend towards energy-efficient and miniaturized loudspeakers with intelligent control algorithms.

In the Hearing, Speech and Audio Technology HSA department in Oldenburg, key technologies are developed for "The Hearing Car". Machines are trained to be able to "hear" in order to minimize downtimes. Robust speech recognizers make devices listen and enable contactless control and quality assurance. In the health sector, speech and language analysis systems are being developed for therapeutic applications and, thanks to mobile EEG systems, the sleeping laboratory comes home. Thanks to algorithms for better speech intelligibility and personalized sound quality, hearables are becoming suitable for the work world – and media use a listening pleasure for everyone.
