Audio services, like voice over IP or several voice recognition systems, are developing very fast and since they are easy to use nearly everybody is linked to such systems. In this thesis about the processing of multiple audio inputs, an audio toolkit for processing multiple audio inputs has to be developed. Used audio input devices are bluetooth headsets, which can send audio via UDP to the audio toolkit. This audio toolkit is able to process these multiple audio inputs and determines a dominant signal. The dominant signal is a signal from a specific client with an audio input device. The focus of the audio toolkit is to suppress every other signal than the dominant signal. The dominant signal can then be transferred to a voice over IP service, like Skype, or to a voice recognition system, like the Microsoft Speech API. This thesis gives a general overview how audio processing works, the development of algorithms which determine the dominant signal and the development process.
