This sound was recorded on a shoot i was on in march, before lock-down. I found when mixing the film that if you apply a cut around the upper-mid range of an eq that you remove a lot of the pressure heard from the exertion of the cork and it sounds more like a bottle cap opening but that's up to you. I'll upload my version of the edited sound as an example.
Popping sound made with my mouth. . . Sounds like a coconut, popping, or knock on the head. No effects used except noise reduction. Recorded at home on conexant smart audio with at2020 mic. Processed on audacity.
Here's some popping sounds i made out of boredom. I just used my mouth to do the popping sounds and edited all of them in audacity. Feel free to use it.
