Abstract A new feature within mobile phones of the third generation is the “advanced audio functionality”. Besides other things, the reproduction of polyphonic ringing tones is of great interest. Therefore, a synthesis unit, which is convenient for mobile phones in respect of memory usage and computational costs is needed. The aim of this diploma thesis is the investigation of sound synthesis techniques, which are suited for these demands. Out of a wide range of different synthesis techniques, three have been chosen to synthesize the sound of a real piano. These are: the FM synthesis, the sampling synthesis and the digital waveguide synthesis. These sound synthesis techniques have been implemented in Matlab™. Thus, the synthetically created piano sounds are compared to that of a real piano.
