Abstract:

In this paper we present a new instrument model to be used for sound modification and interpolation. The approach comprises the analysis of sounds of an instruments sound database, a parameter estimation for the instrument model and a sound synthesis using this model. The sound analysis is carried out by the segmentation of each sound into a sinusoidal and noise component. Both components are modeled using B-splines (basic-splines) in a n-dimensional hyperplane according to the specific sound parameters to capture the instruments timbre for its complete pitch range, possible intensities and temporal evolution. Sound synthesis therein is achieved by exploring these hyperplanes and altering the timbre of the sounds of the database. To conclude a subjective evaluation is presented for comparison with state of the art sound transformations. This work is based on a preliminary study published recently.
