The topic of my thesis is the investigation of the compatibility of channel based and model based sound field reproduction systems. The connection between the two systems technology is the identification and separation of mixed sources, which is still an active research field of digital signal processing. After the introduction I present today's multi-channel sound systems and the difficulties of the source separation. Additionally I present some methods, which are able to solute the problem.

Afterwards I expand particularly the Independent Component Analysis algorithm, its advantages and disadvantages, as well as practicability and conditions of applicability using different sources. I will examine how pre-processing methods can increase efficiency, and explicate my expectations with it.

Then I compare the issues of the implemented algorithms for different signal processing applications and evaluate the results attending to the previous hopes. The paper is closed by summary, where I summarize the results and describe further development opportunities.
