Lite2Sound Photodiode Field Recordings 2: City Streets
Музыка
Just pointing it out the window and cruising the road, sometimes the city broadcasts its own relaxing ambient music.
We are demonstrating the Lite2Sound QB Stereo device from Rare Waves LLC. It captures modulated light from the scene as audio. The audio soundtrack is a recording of fluctuations in light intensity that were captured by a pair of photodiode amplifiers in the Lite2Sound device. The audio is dry, it has not been given any special effects or sound processing.
To make the video, we mounted our Lite2Sound QB Stereo and a miniDVD camcorder on a bar, and connected the Rec output of Lite2Sound to the camcorder’s Mic In with a stereo aux cable. The camcorder’s automatic gain control is active, that is why the noise floor seems to rise and fall.

Dang thats super cool, good idea! You can hear 60hz buzz and all kinds of other weird frequencies. Really captures an intense harsh essence of the urban environment, but unexpectedly musical sometimes. I’m honestly kinda surprised how much signal you’re getting on the car taillights. I would have thought they would just be DC driven, but maybe those are on a PWM circuit or have some kind of noisy switching power supply running them.

Right about the tail lights, 10 years ago it wasn’t as interesting when the tail lights were nearly all incandescent, but now LEDs are in that place, often with a PWM controller built in to every light, I think that explains why we hear something like two oscillators detuned in unison from both tail lights together. As for the PWM frequency, it seems to differ a lot from car to car, which is good fortune here, when they make a pretty harmony. Thanks for your comments!
man this awersome
