I very annoying ringtone I recorded for a stage play.
Used an audio generator to make old-skool cellfone ringtone. 2.1 and 2.5 kHz alternating kinda sine wave.
Noise of an average logitech keyboard. Pretty well recorded (close up), normal style typing (faked though).
16/44 - Chime that could be used for a button click, alert or anything of the like. Reverberated with delay.
A toilet plunging sound (made from editing a sound I can make with my epiglottis).
An electric drill, not drilling, i just pressed the button down. Recorded onto my Minidisc
Concrete blocks tapped with a 5lb sledge hammer. Recorded with AKG condenser microphone to M-Audio Delta AP soundcard
