Audio frequency

Alright kiddo, so you know how when you listen to music or hear people talking or even sound effects in movies, you hear different pitches or tones right? Like the sound of a dog bark is different from the sound of a baby crying or a guitar playing.

Well, those different sounds have something in common: they are all made up of something called audio frequencies. Audio frequencies are just the different vibrations, or waves, that make the sounds you hear.

Think of it like this - when you blow up a balloon and then let it go, it makes a sound, right? The faster you let it go, the higher the pitch of the sound. That's because the balloon is vibrating at a faster, or higher, frequency.

It's the same thing with sound waves. The faster a wave vibrates, the higher the pitch of the sound. So, when someone sings a high note or a bird chirps, those sounds have a high frequency.

On the other hand, if you hear a low sound like a bass drum or a person with a deep voice, those sounds have a low frequency because the waves are moving slower.

In sound systems or music production, it's important to understand frequencies so that you can control and adjust the different parts of a sound to make it sound just right. That way, you can hear all the different parts of a song or movie without any one part being too loud or too quiet.

So, that's what audio frequencies are. They're just the different vibrations or waves that make up the sounds you hear. Cool, huh?
