Clicking sound made by touching my thumbnail to the blades of a moving ceiling fan. Some digital artifacts are audible due to overzealous noise reduction applied after the recording was made.
The sound of an original xbox being turned on, the cd drive being opened and closed, and then turned off again. Recorded with boss br-600 digital recorder.
A clicking noise made by editing a recorded sound of flicking writing utensils into the air. Could make a great selection sound for a game. Edited with audacity.
Clicks from computer, recorded with mobile phone camera. Hum that was caused by computer fan is reduced with audacity. I've uploaded also the original file with no editing.
