Abstract :
In this paper bandwidth enhanced additive sound model with special filter interpolation is presented. This model allows synthesizing new classes of sounds, for example, sounds with harmonics near to analog forte piano sounds. Influence of filter interpolation parameters on different sound characteristics is investigated. Optimized software architecture was developed that allows vectored harmonic processing and parallel note press processing, which allows to implement real-time sound generation.
