In this paper we present a revised and improved version of a re-cently proposed extended source-filter model for sound synthesis, transformation and hybridization of harmonic instruments. This extension focuses mainly on the application for impulsively ex-cited instruments like piano or guitar, but also improves synthesis results for continuously d...

In this paper we present a new technique for sample-based sound synthesis. The approach comprises the analysis of sounds of an instruments sound database, a parameter es-timation for an instrument model and a sound synthesis using this model together with the analyzed sounds. The analysis of the sounds is carried out by the segregation of each soun...

In this paper we present a revised and improved version of a re-cently proposed extended source-filter model for sound synthesis, transformation and hybridization of harmonic instruments.

In this paper we propose a new method for a generalized model representing the time-varying spectral characteristics of quasi -harmonic instruments. This approach comprises a linear source-filter model, a parameter estimation method and a model evalua-tion based on the prototype's variance. The source-filter-model is composed of an excitation sourc...
