My wife blowing into a usb microphone, making a "fwwwwpt!" sound, but reversed to sound like a blowgun. Recorded for the point-and-click adventure game, "the beard in the mirror. ".
This is my sound recording of a large industrial fan blowing (it can be also used for a giant wind blowing for fantasy, horror and sci fi, generously). It is recorded at cheer extreme richmond.
Blowing your nose: a very subtle sound but one that stays true to the common flue. You can hear the tissue crinkling when used, the slight sniffles and also the air escaping the man’s nose. Recorded with the zoom h6, rode ntg in a recording studio. This sound is great to pull focus to someone’s illness.
