Englische Kurzfassung:
While in former times the scientists were exclusively focusing on the hardware oriented preparation of signals (for example filters which were used in stereo cassette recorders to reduce the ground rustling), nowadays with the help of modern computer technics it is possible to digitalize the signals und therefore to prepare them with software tools. This digitalization of the signals means nothing else than to convert the signal into a data
bit stream. Due to various kinds of mathematical concepts (Fourier transform, Wavelets etc.) it is now practicable to analyze these data bit streams and to filter possible noises out of these signals. In this masterthesis the detection of noises in music signals on compact discs, which originate either during the recording (for exapmle microphone hissing) or directly during the production, is
treated. Firstly not only the possible noise types but also the whole mathemtical theory behind (also called signal analysis) are shown, and secondly it will be demonstrated how these mathematical theories can be applied onto real life music signals to detect noises therein. Besides also a short overview, how the ground parts of music, the tones, can be mathematically described and through this description digitalized (also called sampling), is made.
