A very simple string model can be implemented using a single delay line and our simple first-order low pass filter to model frequency-dependent loss.
All losses have been lumped to a single observation point in the delay line, and approximated with our first-order simple low-pass filter
Different sounds can be created by changing this filter.
The Karplus-Strong Algorithm may be interpreted as a feedback comb filter (with lowpassed feedback) or a simplified digital waveguide model.
How do you pluck the string? (noise burst.)
