Karplus-Strong Model

First-order FIR loop filters

H(z) = 0.9 + 0.1 z-1 [wav] [tif]

H(z) = 0.5 + 0.5 z-1 [wav] [tif]

H(z) = 0.1 + 0.9 z-1 [wav] [tif]

Second-order FIR loop filters

H(z) = 0.05 + 0.9 z-1 + 0.05 z-2 [wav] [tif]

H(z) = 1/3 + (1/3) z-1 + (1/3) z-2 [wav] [tif]

H(z) = 0.45 + 0.1 z-1 + 0.45 z-2 [wav] [tif]
