∙ 13y agoTechnically, the sounds aren't "converted". Various electronic devices are used to detect the sounds,
and to impress information onto a radio signal from which similar sounds can be created.
A microphone is used to create an electrical current that varies according to variations in the sounds.
A modulated oscillator or modulated amplifier then uses the varying electrical current from the
microphone to change either the amplitude or frequency of another alternating current, which is
then used to create radio waves.
All of these gadgets together in one package are commonly referred to as a radio "transmitter".
