Device pains you will see soon

This is what I saw. Not only does it know how to manipulate files, sound and audio above what I am capable of doing, but it also knows how to show everyone else what it is supposed to show you, while fooling me. This computer has changed the sound on 6 links online, changed the sound of my mp3 music files, and changed the sound of my video that is on you tube, also online. Then I used the camera within the computer to screen shot it in video form, and it knows how to redit the recorded screenshot to show the correct things. Hence the last two videos here that maybe left you scratching your head. On my pc, it showed me this version, Bit you saw the last two videos version. I figured it out yesterday when I watched the other two on my phone and saw that the sound was in it, I was shocked, embarrassed. It got me again! Not this time.
