I think the fact that it's very chemically stable is likely a factor as well so it can be stored for effectively an infinite amount of time & it won't degrade/react, it'll still be gold.
It's definitely not as exciting as it sounds. It applies a large current through some graphite rods which causes the carbon to evaporate & deposit on a sample sat underneath. It's used to coat electrically insulating samples with a conductive layer of carbon for electron microscopy.
Personally I don't know of any specific research but afaik the reason why our voices sound terrible to us when recorded is because they're missing the bass that's transmitted through the skull, i.e. they sound higher pitched on recording. So I'd try increasing the amplitude of the lower frequencies on the EQ, it'll take a bit of fiddling to get the right balance.
It'll be paraphrased from something a Tory said and I suspect the quotes cover the "paper" from libel since they can then claim it was opinion rather than fact
