Physical Interpretation
- Delay line is initialized with noise (random numbers)
- Therefore, assuming a displacement-wave simulation:
- Initial string displacement = sum of delay-line halves
- Initial string velocity determined by the difference of delay-line halves
- The Karplus-Strong ``string'' is thus plucked and struck
by random amounts along the entire length of the string!
(the ``splucked string''?)
- Karplus-Strong feedback filter corresponds to the
simplest possible damping filter for an ideal string
