The clicking comes from using events rather than smooth signals. If you can rework your math so that line~(or any interpolated full-signal math) outputs directly into the left and right *~ objects which send to left and right out, then that would be best. Otherwise, a quick solution would be to change back into signal using sig~ or number~(in 'signal output mode') and then using rampsmooth~ or slide~ to smooth the signal changes. here's the quick-fix inefficient way based on your patch, note that instead of using rampsmooth~ or slide~ i just set number~ via its inspector to have a ramp time of 10ms, there are much more efficient ways than using number~ but it saves me time in providing you with a workable answer. you should play around with different techniques:
