Multi-microphone systems

The group carries out works on the applications of multi-microphone matrices. The use of several microphones in sound recordings enables the denoising and directional recordings algorithms.

Antyszum is a special tool for extraction of speech recordings made in difficult acoustic conditions. The program is based on adaptive filtering algorithm. Recordings made parallely using several microphones placed in one location allows the separation of useful signals (speech) from signal interferences, like sounds coming from the receiver electronics, appliances, etc.

Microphones can be obscured by other objects, because the program compensates any differences in the characteristics and amplitude of the signals reaching the microphones.
