Unlike most of killer-samples this one is not noise-like or farting-like.

Can you describe what artifacts you can hear with this sample? I only discovered that wasapi event mode produces distortion with my device when playing 48 kHz files, push mode works fine though. I can't abx this sample, perhaps I'm deaf.

First second is enough. There is some weak sibilation in original (to me it seems that it is mostly in right channel), which becomes even weaker in opus.
