Some time ago, I made a post demonstrating these pops with a video. If you’d like to check it out, it’s still available and the video is in the post:
What I noticed is that when the sample is longer than 2 mb, we get this annoying issue. But what I’ve found that works is resampling the sample at a higher pitch and then adjusting it back after bouncing so it matches the original pitch. Usually, pitching it up by +5 semitones makes the sample shorter than 2 mb.
It would be great if we didn’t have to do this, but lately, I’ve been managing fine with this workaround.
