As the radio spectrum is already crowded, there is a need for new medium for faster and more secure wireless communication. To address this problem, a new communication technology called Visible Light Communication (VLC) is introduced. VLC system to transmit an audio signal is presented in this paper. Performance of visible light communication system is tested and analyzed. Besides that, influence of additional amplifier at the receiver on the system is characterized. Results show that the performance of the system is increased by adding the amplifier circuit. Also, the distance between transmitter and receiver can influence the system performance. For longer distances, performance is poor and loss is more. As a conclusion, a visible light communication system for audio transmission is demonstrated and a maximum range of 50 cm is achieved for this system.
