Abstract The Modulation Power Spectrum (MPS) is used to visualize temporal and spectral modulations of sounds. For this purpose the two-dimensional (2D) Fourier transformation of the spectrogram is calculated. In Speech signal processing it has already been shown how modifications (filtering) effect the resynthesized sound in this domain. This master thesis investigates how transformations in the MPS-domain effect other sound material. Transformations like high- and lowpass filtering, moving and suppressing areas and special distortions will be explored.
