There are at least four hundred reasons.
Here are two of them:
#1). If two (or 20) stations in your city all broadcast at audio frequencies,
then you have to listen to them all at the same time, because you have
no way to separate them.
#2). In order for an antenna ... transmitting or receiving .. to do a halfway decent
job, it has to be at least as long as 1/4 wavelength of the signal it's working with.
The shortest radio signal at an audio frequency ... 20 KHz ... is about 9,320 miles long.

What is audio video communication?
Audio transmission is the broadcast of sound, video transmission is the broadcast of motion pictures.
Why dont broadcast stations transmit at audio frequencies?
1) If information was transmitted at audio frequencies, then you would actually hear the signal. This would be identical to a speaker playing a song on your stereo. 2) Audio frequencies, in the world of radio frequencies, are long wave-length, low energy signals that can't travel long distances. Again, that's why you can only hear someone's stereo from within eyesight of the system. Human ears can detect from about 3Hz up to around 20KHz (some better than others). 3) True radio frequencies start at in the 100Khz range. This is your most basic radio that uses amplitude modulation (aka AM radio). Many people today that listen to the radio listen to frequency modulated (FM) stations. The difference between AM and FM is beyond the scope of the answer to this question. Being a higher frequency, the signals have more energy and can travel farther distances than audible frequencies. 4) Audible frequencies (sounds the human ear can pick up) can only "transmit" amplitude (loudness or volume) and frequency (high or low pitch). However, higher frequencies, such as those used for radio, can carry much more information than the volume and pitch of a signal. This is a direct result of radio frequencies being harmonics (integer multiples) of audible signals. For instance, if a radio signal has a frequency 20 times higher than the audio signal it is transmitting, then that radio signal can not only carry the audio signal, it can also carry other information, such as information about the broadcast station. A radio signal can "encode" information within the signal allowing more information to be carried than just the audio signal itself.
Why do radio stations use FM for high quality music?
FM is not used to broadcast high quality music. FM is how the broadcast is carried out on to the airwaves. The high quality sound comes from the stations transmitter, compression, and different equipment to give the audio a good, crystal clear sound. Hope this helps!

What radio stations in the San Francisco Bay Area broadcast Michael Savage's radio show?
He is on KSTE Radio (650 AM) which says its signal reaches the San Francisco bay area. He is also online via streaming audio from a number of his affiliated stations.
Can you get AM stations on DAB radios?
No, DAB (Digital Audio Broadcasting) radios do not receive AM stations. DAB is designed for digital broadcasting and operates on different frequencies compared to AM (Amplitude Modulation) and FM (Frequency Modulation) radio. If you want to listen to AM stations, you'll need a traditional AM radio or a device that specifically supports AM broadcasting.
How do low frequencies affect the quality of sound in audio recordings?
Low frequencies can impact the quality of sound in audio recordings by adding depth and richness to the overall sound. However, excessive low frequencies can cause muddiness and distortion, affecting the clarity and balance of the audio.
How many radio stations broacast the Ed Schultz program?
About 90 radio stations currently broadcast the Ed Schultz program. The number varies, however, as affiliates come and go. Ed Schultz's radio show is also broadcast by Sirius/XM satellite, on channel 127. And the radio show is available via streaming audio on the Ed Schultz website.
What is an audio frequency?
An audio frequency is a frequency, or range of frequencies, of audible sound waves.

When you listen to the radio why are you able to hear only one station at a time rather than all stations at once?
When you listen to the radio, your receiver is tuned to a specific frequency, allowing it to capture and decode the signal from that particular station. Radio stations broadcast their signals on different frequencies, and the receiver selectively amplifies the signal from the chosen frequency while filtering out others. This selective tuning is made possible by the design of the radio's circuits, which isolate the desired signal and suppress interference from other stations. As a result, you can enjoy clear audio from just one station at a time.
Which audio cable is able to release all audio frequencies without causing a delay?
Audio cables don't cause delays.
