Just like there are ways to capture invisible (cloaked) demons with a digital camera , there are also ways to capture cloaked speech. Like all sound, sounds (or speech) made by cloaked demons propogate through air, but air that is a mix of cloaked and non-cloaked (native) molecules. The volume of any sound a cloaked demon makes is in direct proportion to the ratio of cloaked to non-cloaked molecules—the more air molecules native to our realm, the louder the sound will be. A digital recorder can be imprinted with sound waves outside of the range of human hearing, and those that are outside of that range (as they would be if a demon is speaking while cloaked) can be (and is) redigitized to a range inside that which a human can hear. NOTE | Cloaking doesn't just alter visibility, it alters time, too; that's why cloaked demons are usually only captured in one to three still frames on video (and never in images made one-at-a-time). The same principle applies to audio recordings.
