Infrared audio transmitter with carrier signal

Infrared transmitter and receiver for audio transmission. The advantage of using a carrier signal is that there´s no buzzing sound if you turn on the light. There are several easy "infrared transmitter" circuits in the internet - most of them consist just a few parts - which do have a nice audio quallity but get strong affected by other "light sources".

here is the link for the circuit: http://img815.imageshack.us/i/infraredsystem.gif/
