Very good quality recording of a pleasant sound. I've used it as part of the background ambience in a game I made (see the 'Incredible Adventures of Chi' at http://www.nholz.com ). It was made as part of a project organised by a charity I've been volunteering for. I've credited you in the acknowledgements and put a link to your profile.
That would completely defeat the purpose of using FLAC. You *can* use this sound in After Effects, Sound Forge, Soundtrack Pro, Audacity, and a multitude of other audio editors. You just need to convert it from FLAC to the format desired by your audio editor of choice.

Should've quit smoking a couple years earlier, I guess! :) I wanted to do it all in one take to try to keep the tone as similar as possible between numbers, although that didn't hold true near the end after I decided to add in the extra building blocks.
