Objectives: With the rapid development in the Light Emitting Diode (LED) it leads a path for the development of the next generation data communication named as Visible Light Communication (VLC). VLC replaces Radio Frequency communication by giving higher and better bandwidth and a very high data rate. In the present day life we use a lot of LED based lights for illumination. Methods/Analysis: The LEDs are also used alternatively for Communication. This has many advantages like high duration, safety, high efficiency and Flickering rate. Findings: The visible light can be used extensively to transmit the audio signals and this is done by the presence of the normal White LEDs. Applications: Solar panels are used in the receiver section to which an amplifier and speaker are connected to recover the transmitted signal.
