Acoustic Communi­cation Enhancement



Easy and relaxed conversations everywhere

Acoustic communication enhancement (ACE) is the sonoware software solution for speech or audio requirements in your individual product - tailored to your needs.

An example of ACE in the operating room

In the operating room hitch-free communication is vitally important. However, there are numerous electrical devices that produce noise or behave as obstacles in the speech paths.

Our ACE system improves this situation by combining microphones, loudspeakers, and optimized algorithms to distribute speech and therefore provides the foundation for more efficient surgeries. The system can be integrated into medical devices or into the furnishing of the operating room.

More use cases of ACE

ACE is not restricted to medical environments. Generally, it simplifies speech communication in all environments that suffer from high-level background noise or moderately large distances between the interlocutors. ACE addresses all these challenges and ensures hassle-free communication in environments, such as PA systems, conference rooms, audio/video chat, etc.



All sonoware signal processing algorithms are optimized for minimal-delay, low computational complexity and maximum portability across platforms. In order to account for different acoustic conditions in setups with multiple zones, all algorithms are optimized for each recording/playback node indivdually.
