AB  - Wave propagation along springs in a spring reverberator is studied, and digital emulations of several popular spring reverberator models are presented. Measurements on a number of springs reveal several dispersive propagation modes and evidence of coupling among them. The torsional mode typically used by spring reverberators is seen to be highly dispersive, giving the spring its characteristic sound. Spring reverberators often have several springs operating in parallel, and the emulations presented here use a set of parallel waveguide structures, one for each spring element. The waveguides explicitly compute the left-going and right-going torsional waves, including dispersion, propagation and reflection effects. Scattering from spring imperfections and from the rings coupling counter-wound springs are modeled via waveguide scattering junctions.
