a system and a method for simulation of nonlinear audio equipment

摘要

A dynamic non-linearity model satisfying a static non-linear function, corresponding to device to be emulated, receives the input audio signal through an interface and outputs the audio signal through an interface. A mode estimator receives the input and output signals of the dynamic non-linearity model for estimating the operating mode of the model and feeds its output to the model. Independent claims are also included for the following: (1) computer program product for estimating parameters in a tube model and simulation of the model; (2) method for estimating parameters in a tube model and simulation of the model; (3) computer program product for simulating linear components of audio equipment; (4) method for simulating linear components of audio equipment; (5) computer program product for controlling the dynamics of linear components of audio equipment; and (6) method for controlling the dynamics of linear components of audio equipment.
