Physical model; two tube sections with scattering junction inbetween; their relative areas determine k.
Excitation to inject into the system
Scattering coefficient for junction of two tubes, usually -1<=k<=1
Amplitude loss factor in circulation
Length in samples of first delay line
Length in samples of second delay line (no interpolation implemented yet)
