versatile, creative, product-oriented

From initial idea to design and construction of the demonstrator to acoustic end-of-line inspection: We can develop audio system solutions for you according to your individual requirements and help you with hardware design, selection of components and algorithms as well as software applications.

Audio System Technology

Processes in the field of audio system technology are part of the core expertise of the Hearing, Speech and Audio Technology Division (HSA). Our researchers develop technologies for audio system solutions, including hardware design, selection of components and algorithms as well as software applications. They span the whole process – from the first initial idea to the design phase and cooperation with partners to acoustic end-of-line inspection in production. The main strengths of the Fraunhofer IDMT lie, among others, in pattern recognition, machine learning and human-technology interaction.

Press Release / 14.6.2016

Industrie 4.0 learns how to hear

In the joint project ACME 4.0, partners from industry and research will investigate the potential of acoustically monitoring machines and production processes. The goal is to develop an energy-autonomous, highly-integrated sensor platform that can be integrated wirelessly in industrial installations.

 

Dereverberation and reverberation of audio, music, and speech

In the Marie-Curie Initial Training Network »DREAMS (Dereverberation and Reverberation of Audio, Music, and Speech)«, Fraunhofer IDMT develops signal processing strategies designed to remove reverberation components.
