It’s a gain structure smoothing tool. It can be applied over any distortion type/ The only condition is that it can be applied on a white noise alike signal so miced up cabinet recording won’t work with it. Smoother works in its best way at 44100Hz samplerate and has 64 sample latency. It works with 48000Hz samplerate as well.
Circled X is the multiplication process.

USAGE: Put it after amp simulator/amplifier/distortion but before impulse convoler e.g cabinet simulator. You can shape the harmonics sound by putting an EQ in front of smoother.
