These are some nice UI sounds! If you're interested in learning more about the use of sounds in UI, I have a blog just about that called Beyond The Beep http://beyondthebeep.tumblr.com

Interesting, although without videos or animations along with the sounds it's not very effective. I don't get the feel for the UI with text/sounds/static images.

I second the comment about the lack of videos / gifs.

Also, what websites would you use if you'd needed sounds for your app?
