Signal Model Based Synthesis of the Sound of Organ Flue Pipes
1998 - 1999
Offering small, portable and more economical organs for home, studio and stage applications is a long-standing problem in the research of sound synthesis methods. The well-known PCM or Sampling synthesis, which records the sound, loops it and plays it back cannot take into account the stochastic parameters of the sound. During this project, another method has been developed, which models also these effects.
Signal model based synthesis could be a well-balanced compromise between computation efficiency and sound quality. As most of the musical instruments generate nearly periodic sound, the signal model is based on the discrete-time model of the periodic signals.
The final organ-model has been set during the experiments. The model has three part with three different function:
During the project, the following methods have been developed:
