Audio forensics for law enforcement

Our forensic analysis tools precisely examine audio and video material for manipulations, synthesis, origins, and authenticity. Technologies such as coding analysis and synthesis detection reliably identify alterations. These analyses help investigative authorities evaluate the evidentiary value and integrity of media materials.

Detection of manipulation, synthesis, and reuse of audio material

Our audio-based analysis methods reliably detect manipulations such as cuts, AI synthesis, recording tracks and the reuse of audio material. This speeds up verification and detects subtle changes.

Audiofields – 3D audio for entertainment, communication, and driving safety

Audiofields provides a consistent 3D audio experience across various vehicle platforms and speaker configurations. The technology simplifies the integration of entertainment, communication, and safety functions into modern vehicle architectures.

Acoustic bridge monitoring

We monitor bridge decks using acoustic sensors and AI. Analyzing bridge sounds enables early detection of structural changes – for increased safety and reliable, continuous monitoring.

Technology-based analysis of children's language for early support

Our AI algorithms identify speech and language development issues early on—enabling targeted support and better educational opportunities.

Optimized speech intelligibility, music playback, and safety in the driver's cab

Our technology ensures that voice communication works reliably in noisy cabs—both for drivers and for the people they’re talking to on the other end of the line. This significantly enhances safety, ease of use, and customer satisfaction.

Wir machen Sprachverständlichkeit in Film und Fernsehen mess- und optimierbar – in Echtzeit.

Optimizing speech intelligibility in film and broadcast media

We make speech intelligibility in film and television measurable and optimizable—in real time. The “Listening Effort Meter” helps audio professionals create content that is easy to understand, leading to a more satisfied audience.

Speech training – mobile and independent

Our mobile speech training program enables users to improve their communication skills in a flexible and self-directed manner. Digital technologies specifically support the success of the training—regardless of time and place and in line with individual goals.
