This video demonstrates experimental audio field recording using a Lite2Sound device plugged into the camcorder’s Mic Input. This scene is the shoreline of Lake Charles, Louisiana beneath the Calcasieu River Bridge.
The sounds in this video were recorded without any microphone. I’m demonstrating a photodiode audio device, Lite2Sound HD Stereo 40mm. Lite2Sound lets you hear sounds emitted by lights, and I have it plugged into the camcorder’s Mic input. The sensors in this device are 200 times larger than in Lite2Sound PX. That gives it a huge improvement in noise floor. And so it easily picks up sounds from lights that are far away. You can use it to hunt for new sounds at night. I look for locations and scenes where many lights are blending together, such as this shoreline scene near a busy bridge.
I’m attempting to shoot steady video without a tripod, while under attack from gigantic Louisiana mosquitos. But I’m not a serious videographer. This is about audio.
The sounds like car horns are actually oscillators in the headlamps. When moving lights are passing behind periodic barriers, such as the ironwork railing on the Calcasieu River Bridge, the steady tones are interrupted into series of pulses. Distant lights often pick up the sound of air turbulence.
A synthesizer has oscillators, envelope generators, noise sources, mixers. Here it seems like the world has evolved its own type of sound synthesis. There’s a sound track hidden in the ambient light from ordinary things.
Let us build you a custom Lite2Sound device with this level of performance.
