Heard a really interesting sound while doing recordings with glass, and decided to amplify it. Good for a menu sound in a game. Other version: https://freesound. Org/people/nightflame/sounds/397604/.
A short soft whistle suitable for "onhover" mouse events when constructing various menus. Created using audacity, by applying a couple of filters and changing a pitch of a short whistle - my own whistle.
