Motion-magnified Bag of Chips

We use our motion magnification technique to visualize motions in a bag of chips induced by sound.
At the bottom are four videos, each magnifying motions at a frequency corresponding to one of the four dominant tones in MIDI music we played close to the bag of chips. Each motion-magnified video is highlighted when its corresponding note is played. (all the videos are playing throughout the clip, but motions at each frequency are visible only when the corresponding note is playing)

Interesting, thanks for sharing.
At the end of each note the frequencies spread out, does that show up in a microphone recording?
Do you subtract lower frequencies carried in through the building, like by a heavy truck driving by outside?

Hi Miki.. Hope you're doing well..
I am interested in studying the passive sound recognition as a supplementary for my MSc studies, and after checking your work I was really amazed with the results you got. Thus, and because I am still at the beginning of the work, I need some help for the methodology used to get the results. I will be happy if you provided me with your email so I can contact you later.
Keep up the good work.

Nah, this has been picked up by those who can’t be mentioned on here. They use it to hear everything, because sound is vibration. Good luck
