What is Audio frequency

Audio frequency

Audio frequency refers to the speed of sound vibrations, measured in Hertz (Hz), which determines how high or low a musical note sounds to our ears. Imagine plucking a guitar string – when it vibrates rapidly, it produces a high-pitched sound, and when it vibrates more slowly, it creates a low-pitched sound. This concept applies to all musical instruments and even our own voices!

Now, let’s delve a little deeper. In music, there are different ranges of audio frequencies that contribute to the overall sound. The human ear can typically hear sounds in the range of 20 Hz to 20,000 Hz. Frequencies below 20 Hz are called “infrasound,” which we can’t hear but can feel as vibrations. Frequencies above 20,000 Hz are called “ultrasound,” which are also inaudible to humans but have applications in certain technologies.

In modern music production, understanding audio frequency is vital for creating a balanced and pleasant listening experience. For instance, when mixing a song, a producer adjusts the levels of different frequencies to make sure each instrument and voice can be heard clearly. If there’s too much bass, the song might sound boomy and overpowering, while excessive treble can make it harsh and ear-piercing.

Let’s take a pop song as an example. In a contemporary track, you’ll often find the bass guitar and kick drum occupying the lower frequency range, providing a solid foundation to the song. The vocals and melodic instruments like guitars and keyboards reside in the mid-frequency range, ensuring clarity and warmth. Finally, the cymbals and high-pitched synths fill the upper frequency range, adding sparkle and brightness.

In summary, audio frequency is all about the speed of sound vibrations and determines whether a musical note sounds high or low. It plays a crucial role in shaping the character of music and sound that we hear every day.
