Some reseach at first

Oh well, here we are. I've never met with sensors, so I tried reading on wikipedia a little bit... "A sensor is a converter that measures a physical quantity and converts it into a signal which can be read by an observer or by an (today mostly electronic) instrument. For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, most sensors are calibrated against known standards." it began, but it sounds more like black magic or whatever.

Hehe, when you type "sensored sound" on google, you'll find "censored sound" and it's really NOT what I'm looking for, but on youtube I found something that looks quite interesting:

 Seems like the lights are behaving according to what the music plays. That's a really nice thing!

Or this used as part of car tuning.

Here how it works with different music:

They even produce T-shirts with it. I'd never expect! Though not that much surprising

But this is amazing!! I stopped seeing the building at some point!

At this point I'm wondering if there is something else that sound can control OR how the sound can be controlled. Not sure if it's about this, but simple wondering :)
