Double click from a computer mouse
Quick random series of high pitch beeps modulating quickly
Pulsating dirty bass 'heartbeat'with pitch bent vocal pads, quick zaps
Ascending series of computerized high pitch bleeps
Sound design alert: medium-pitched alert with delay
Bright brief zap followed by double bubbly bassy punctuations
Computer voice from a Boeing 757 cockpit saying 'current faults, no faults'
Long repeated ascending zaps with musical bleeps and glassy overtones
Typing on a computer keyboard
Dirty panned multi-tonal drones & hi-frequecy 'digital chatter'
