| 描述： | Moving the Colorino around on the front of my Lifecam HD3000 as the little working light is on. It's a tiny light, so tricky to find the center of it. Like many LED's that aren't running directly off AC power this produces a clear tone, no modulation except for that caused by my moving the probe around it.The Colorino Talking Color Identifier and Light Probe produces a tone when you hold down the light probe button. It's a pocket sized 2in1 unit, which is a Color Identifier/Light Detector for the blind and colorblind. The stronger the light source, the higher the pitch. The more light it receives, the higher the pitch. So you can vary the pitch by moving and turning it.Recorded from linein on my desktop using Goldwave. Lowpass filter was applied to lock out the 16khz sampling frequency. |
