The topic of my thesis is the development of an airplane sound synthesizer iPad application, which is built on the basics of the Sound Synthesis Machine developed in the COSMA 7th framework EU project. In my thesis I will present the necessary things to the developement, like Apple's new programming language the Swift, the necessary programs for this and the latest mobile operating system, iOS 8. I will discuss the most important new features of iOS 8, which are expected to revolutionize the mobile market development in the future. I will introduce the European Project, in which the Budapest University of Technology and Economics, Department of Networked Systems and Services was one of the key partners. The project was about lowering the annoyance of airport communities caused by aircraft noise. One of the tasks was the development of a sound mixing software, which I will present in details. In the most important part of my thesis, I will introduce the development process and the details of my application, covering the problems, which were induced by the iOS platform and the solution of these.
