I missed this sound sample because it didn't have the usual format - but this is extremely useful.
It is NOT a grounding issue, because ground loops are always loud and low (50 or 60Hz) plus a little of the harmonics. This is a high frequency that has data on it - you can hear it. It's coming from the processors, and is generated by the computer internally. It shouldn't of course, be on the audio, but many external and internal audio interfaces handle this very badly, and sometimes it's because of grounding issues, but mostly just poor design of more than one component that on their own, work just about acceptably, but when combined - all hell breaks loose!
The solution is a proper microphone, a proper interface and a computer with a motherboard that people have had success using for audio. Once all these good bits are in place - success is usually guaranteed.
