  • System and method for simulation of non-linear audio equipment
    Patent number: 8165309
    Abstract: The invention describes an apparatus for software or hardware emulation of electronic audio equipment, which characterizes a non-linear behavior. The invention comprises an analog to digital interface (504) for the input audio signal (502), whose output (506) is communicatively coupled to a dynamic non-linearity (508). The output (514) of this dynamic non-linearity is finally communicatively coupled to an interface (516) producing the output audio signal (518). The dynamic non-linearity consists of a mode switching static non-linear function, where the mode parameter (512) is estimated in a function (510) based on the previous values on the input (506) and output (514) of the dynamic non-linearity.
