Flaccon,
Okay, now I'm really confused.

I thought I understood your explanation of how the voices entered recordings, or rather your best guess as to how it happens - I get that you're not claiming to possess any high-tech skills and can only share your personal observations - but I'm afraid I may have "overthought" to a point of completely misunderstanding the process. If I have, I apologize.
Would you (or anyone here) clarify some things to help me out?
_ Regarding the earlier recordings discussed here: These recordings needed to be made in a quiet environment so that the spirits' voices would easily stand out in playback. Recording with the microphone muted wouldn't work because the spirits use wires and cables (channeling through flaccon's fingers) to enter the file, not the computer itself. Muting the microphone cuts off the path they travel. Is this correct?
The spirits insert words into the recording as you (flaccon) listen to the playback, not during the recording itself. If you sent someone a copy of the recording before you listened to it, that copy would remain unaltered, unless you "calibrated" that person's computer, as you did with Mr. Roberts' (Scrappy's) laptop in mid-June. Once a computer is calibrated, voices will be heard in recordings made by that person; a kind of chain-reaction occurs. Is this correct?
_ Regarding the YouTube videos: The videos are altered in the same manner as the private recordings, using you (flaccon) as the conduit to access the file. The spirits require both flaccon's physical presence and electric wires and cables. In other words, Scrappy playing a video to flaccon over a phone line has no effect. Once flaccon views the YouTube video on her computer, words are added and when Scrappy replays the same clip, he hears the altered version. Is this correct?
Also, does the video need to be refreshed, or will the inserted words be heard even if it's replayed from the browser cache or from a local copy saved to a personal computer using a video capture app?
Calibrating individual computers is no longer necessary. Flaccon's physical self is still required, but the spirits have learned how to alter the original (uploader's) copy independently. The result is that anyone viewing the video will hear the voices. I'm not being facetious; I accept that they are capable of learning. Is this correct?
_ Regarding the original file: Does that refer to the file on YouTube's server?
_ Regarding the images: The spirits urged you to closely examine (your) bloodstains on a shirt. Doing so, you discovered there were images in them, mostly faces. So far you've found about 60 images in these bloodstains. Is this correct?
The spirits also urged you to have the blood tested, which you did and are currently awaiting the results of the tests. Is this correct?
The spirits are now producing images in tiny flicks of paint. These images are new and not part of the 60 original images. Is this correct?
Sorry for asking so many questions. I'm comfortable sharing my opinions here but they're meaningless if I have the facts all wrong. If I've made a hot mess of your comments, I apologize and look forward to being corrected. Thank you!
