Lite2Sound HD Stereo photodiode field recording - Eugene, OR

video upload by EA78751

"The location is Skinner Butte in Eugene, Oregon, and this video is demonstration of an experimental field recording device called Lite2Sound HD Stereo 62mm. The waveforms in the audio soundtrack are being emitted by the lights in the scene. Lite2Sound uses photodiodes as sensors to convert fluctuations in light intensity directly to audio. The device I used for this video has sensors 200 times larger than our basic model, Lite2Sound PX. That gives it much greater sensitivity, so its possible to hear many lights blending together, even from miles away.

Every city sounds different..? A serious videographer could do awesome things with this. I have built four Lite2Sound HD Stereo devices, and they are available, please inquire. I can be contacted through rarewaves.net.

I noticed in this video there is an invisible infrared light somewhere in downtown Eugene that emits strong pulses at 1-second intervals. It sounds like a ticking clock, but since you can't see any corresponding blinking in the video, it must be infrared. I assume it is providing flash illumination for some sort of slow-frame night surveillance camera. These are more common in urban areas now, who's watching who?

Thanks for watching!
