Rudimentary Laser Microphone Drum Kit Test

Dollar store laser pointer on top of tripod, bounces off window, captured by optical sensor, fed into recorder via 1/4". This is my first "successful" test, but the noise is just outrageous. Used many layers of noise reduction and normalization + a small amount of dynamics.

So the laser picks up the vibrations in the glass created by the kit, right?

Interesting concept. Original!

Yep, that simple. Eventually I will try another one with a smaller sensor that more closely matches the size of the laser beam. After that...I guess I start looking for a more powerful "Laser". Will probably also try using a larger window for more modulation.

@killacam44 an infrared laser can be used in this case!!!

@tuttlesoundlabs if u use a more powerful laser then ur neighbors will see the beam and cal the cops lol

What kind of program did you use to see the sound waves? I was trying to find a program but i couldn't oh and does it have recording to record?

didn't I see such a set up in the movie "Jade" ?
