from one of my movies of my leg but you can't see the muscle jerk from the signal so i just recorded

Not amplified but this is from my pen camera earlier I was trying to catch them manipulating my leg but you can't see it good in the movie so I recorded the audio instead.
I think the spikes in noise is when my muscle moved in my leg especially at the end there's a big spike in noise in the v2k
notice the kids voices too
