Skype interference or feedback sound effect. Its the sound your computer makes if your speakers are too loud. What happens is that your computer plays the sound coming from the person on the other side and then it plays over there and then plays back on your computer, it builds up in waves. Just turn your sound down and it should go away.

I drove my car into a wall; and recorded the proximity alert from it. I then washed it through audacity; slowed it 23%; and trimmed the edges. The result? -chilling. A few indistinct gulps cool the atmosphere a little more. It's not the making of a corpse - but it sounds a bit like it?. Recorded late at night in my car by my home with the engine off in fog - so the sound is 'hollowed' by the atmosphere. Recorded using a sennheiser mke300 'shotgun' mic. Cropped in audacity; and saved as aif file. What a chilling way to go. . . ?.
