how do I get rid of this crackling sound?

[wanton heron]

have you tried eqing it? if you're lucky you may be able to eq out the popping

of course that's assuming that the intended sound ends up being in a different frequency range than the popping sound

hmm, idk then. I'm not familiar with serum so i probably wont be of any further help. But i did a quick search on youtube and found this video, maybe it'll prove helpful idk. But hopefully you can find a solution https://www.youtube.com/watch?v=bBSGXADPkb0&ab_channel=ADSRMusicProductionTutorials
