What are Frequencies?

Frequencies refer to the rate at which sound waves vibrate over time. In audio and music, frequency determines the pitch of a sound, meaning how high or low a tone is perceived by the listener.

Frequency is measured in Hertz (Hz), which represents the number of vibrations or cycles that occur per second. Lower frequencies produce deep bass sounds, while higher frequencies create brighter and sharper tones.

The range of frequencies that humans can typically hear extends from about 20 Hz to 20,000 Hz (20 kHz). Different parts of this range correspond to different types of sounds, such as bass, midrange, and treble frequencies.

In music production and audio engineering, frequencies are often shaped using tools such as equalizers, filters, and audio processors. These adjustments are commonly made within digital audio workstations such as Ableton Live, FL Studio, and Logic Pro to balance the sound of different elements in a mix.
