A simple waveguide model consisting of one delay-line and one first-order lowpass filter.
asig -- the input of excitation noise
xfreq -- the frequency (i.e. the inverse of delay time) Changed to x-rate in Csound version 3.59.
kcutoff -- the filter cutoff frequency in Hz.
kfeedback -- the feedback factor
wguide1 is the most elemental waveguide model, consisting of one delay-line and one first-order lowpass filter.
Implementing waveguide algorithms as opcodes, instead of orc instruments, allows the user to set kr different than sr, allowing better performance particulary when using real-time.
