A high fidelity simulation of a plucked string, using interpolating delay-lines. This controls the overall decay of the string. The greater the value of idamp1, the faster the decay. Negative values will cause an increase in output over time.
Higher values cause the higher harmonics to decay faster.
The decay of the virtual string is controlled by idamp and ifilt which simulate the bridge . The oscillation is sampled at the point kpick , and excited by the signal axcite .
