The sound of heavy rain on the metal casing of an air conditioner. Also some soft thunder and my dad clanking around in another room. Recorded 4 miles north of Lisbon, OH during a June 16 Thunderstorm. I recorded this with my CAD U1 USB Mic and my Toshiba laptop using Audacity.<br/>在AC.wav上下雨<br/>聲道：2<br/>類型：wav<br/>Rain、Thunderstorm、Air-Conditioner、Storm、Ohio<br/>雨、雷雨、冷氣機、風暴、俄亥俄州<br/>資料來源：freesound ( https://freesound.org )

Moving the Colorino along the plastic grill of a box-fan that is turned off, which is between the probe and the sunlight from the window.The grid pattern interrupts the light as I move it along, giving the received light a warbling modulation.The Colorino Talking Color Identifier and Light Probe produces a tone when you hold down the light probe button. It's a pocket sized 2-in-1 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 line-in on my desktop using Goldwave. Low-pass filter was applied to lock out the 16khz sampling frequency.<br/>聲道：2<br/>類型：wav<br/>experimental、playing、grid、natural-light、fm、Assistive-technology、modulated-light、fan、warble、modulation、noise、frequency-modulation、squares、light-to-sound、sunlight、wobble、color-detector、electronic、light-probe、accessibility、color-blind、tone、blind<br/>資料來源：freesound ( https://freesound.org )

I also changed the carrier to a triangle wave.This was the result. Also in this file, the carrier tone has not been completely removed.<br/>聲道：1<br/>類型：wav<br/>experimental、tv-remote、demodulated、light-to-sound、processed、Audacity、image-to-sound、light-probe、modulated-light、Nyquist-prompt<br/>資料來源：freesound ( https://freesound.org )
