In this video, we are using the IR LED to beam a music signal to a Light Sensor attached to a Speaker. At first the signal is very weak because the visible light is drowning out the infrared signal. When we turn on a nearby lamp, the infrared signal becomes totally drowned out and the music stops. However, when we put an infrared filter over the Light Sensor, the music comes back louder than ever.
