What does the equalizer do?

Question

As far as I can tell, it makes some sounds louder and others quieter. Can someone explain with a metaphor or visual what it’s doing?

Answer 1

Sound that you hear covers a broad range of frequencies – from 20 hertz (very low, bassy sounds) to 20,000 hertz (very high, shrill sounds).

The equalizer allows you to adjust the volume of the specific frequency ranges independently. So if you feel that your audio system is too shrill, you can lower just the high-frequency volume without also reducing the volume of low or mid-range sounds.
