What is the role of a radio transmitter?

The primary role of a radio transmitter is to convert audio signals into radio waves suitable for transmission over the air. When audio input, such as music or voice, is processed within the transmitter, it modulates this information onto a carrier wave, creating radio waves that can propagate through the air. These radio waves can then be received by radios tuned to the correct frequency, allowing listeners to access the content being broadcast. Other options describe functions not directly tied to the core purpose of a transmitter. For example, storing audio files for later broadcasting relates more to a server or playback device rather than a transmitter. Amplifying radio waves is a function associated with repeaters or boosters, which enhance the signal after it has been transmitted. Selecting the frequency of transmission is part of the overall process of setting up and operating a transmitter but does not accurately define its main role in converting signals for broadcast.
