This was recorded by holding a small pcm recorder (zoom h1n) very close to an ipod 4th generation. The ipod was turned on and its hard drive tried to start up. You can hear the spin up of the motor and the hard drive head clicking back and forth. The hard drive fails to power up completely and eventually shuts down again. A 350 hz high pass filter was applied, in addition to audacity noise reduction, to get this clean motor noise from the original recording. The stereo file was then mixed to mono because the mic was slightly off center from the ipod, and the stereo provides no benefit. The hard drive in this ipod is a 1. 8" 40 gb toshiba hard drive, the ipod model is a1059. The microphone was held just 3 cm (1. 2 in) from the ipod. Recording settings were stereo 44. 1 khz at 16 bit (wav format). The file is the same except it's mono.
