How do you modulate audio sound into FM?

Answer:
Walmart and Radioshack sell FM modulators. these are mostly used to send audio from a I- POD or other device to a FM car radio tuned to the frequency of the modulator, some are switchable to avoid the frequency of any local FM radio station. For use at home get a power supply to power it from a wall socket. Some are stereo and some are mono.
