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.
A sound used for gui cancel button clicks. Created using audacity with two sinusoids (in inverted order, compared to the original sound) with fade-in fade-out effect.
Anime laser sounds of different lengths. You could use them as a transformation/laser sound effect or use the shorter ones as gui sounds. Made in vstron.
