Embodiment Construction

[0036] Referring to the accompanying drawings, a system for generating synthesized sounds in a musical instrument according to the invention, generally indicated by reference numeral 100, is described.

[0037] The system 100 allows estimating parameters of a physical model of a control instrument. Specifically, the system 100 was applied to a model of a church organ, but can generally be used with many types of physical models.

[0038] refer to figure 1 , the original audio signal S IN enters the system 100 and is processed to obtain a synthesized audio signal S emitted by the system 100 OUT .

[0039] refer to Figure 1A and Figure 1B , the system 100 includes:

[0040] - First stage 1, where the original signal S is extracted IN and evaluate the parameters of said features F, in this way obtain a number of evaluated parameters P* 1 ,...P* M ;

[0041] - Second stage 2, where the evaluated parameters P* are used 1 ,...P* M to obtain multiple physical models M ...

Abstract

A generation system (100) of synthesized sound comprises: a first stage (1), wherein features (F) are extracted from an input raw sound and parameters of said features are evaluated; a second stage (2) wherein the evaluated parameters are used to create a plurality of physical models that are metrically evaluated in order to find the parameters of the best physical model, and a third stage (3) wherein the parameters of the best physical model are perturbed in order to create perturbed physical models and a metric evaluated of the perturbed physical models is performed to find the parameters ofthe best physical model.

Description

technical field [0001] The present invention relates to a system for generating synthesized sounds in musical instruments, especially church organs. The parameterization of the physical model is used to generate synthetic sounds. The invention relates to a parametric system for generating a physical model of sound. Background technique [0002] A physical model is a mathematical representation of a natural process or phenomenon. In the present invention, modeling is applied to organ pipes, resulting in a true physical representation of the instrument. Such a method allows obtaining musical instruments capable of reproducing not only sounds but also the associated sound-generating processes. [0003] US7442869 in the name of the same applicant discloses a reference physical model for a church organ. [0004] However, it must be considered that a physical model is not strictly related to the generation of sound and its use in musical instruments, but can also be a mathemat...
