Abstract:
1. A stringed instrument with embedded digital signal processing (DSP) modeling capabilities to model an acoustic stringed instrument, the stringed instrument having a body and at least one string, the stringed instrument comprising: a pickup to which a string is coupled, the pickup to detect a vibration signal of the string; an analog to digital converter to convert the detected vibration signal of the string into a digital string vibration signal; and a digital signal processor located within the body of the stringed instrument to implement an acoustic modeling system to process the digital string vibration signal to emulate a corresponding string tone of an acoustic stringed instrument selected for modeling to create an output emulated acoustic digital string signal, wherein the emulation of the corresponding string tone of the acoustic stringed instrument further includes modeling a body of the acoustic stringed instrument including modeling the relationship of a string to a soundboard of the body of the acoustic stringed instrument to be emulated based on the mechanical admittance of the string to the soundboard utilizing modeling coefficients and filtering the digital string vibration signal based on the model of the body of the acoustic stringed instrument selected for modeling.
