Hello Stayf,
thanks for the kind words regarding to vocoder V!
if you want to reduce these hiss/clicks/pops you can use the balance knob located right of the vocoder Area, as seen on screenshot below. if you set it fully to the right (buzz), these sounds will be shut. But depending on the audio recording, you may still have some of these. you can also in this case set high freq level (knob above) to minimum .
hope it helps,
best,
