Sound > Control > Equalization


ABOVE: There are seemingly millions of buttons on an audio board--many are dedicated to adjusting EQ. In this clip (no sound), the board operator adjusts the treble.

BELOW: You have probably played with EQ to boost your favorite music--but what effect does it have on the human voice? Below are a couple examples that let you hear for yourself. First, a voice with NO equalization...

Next, listen to the voice with a big bass boost....

Finally, listen to the voice with a treble boost...

"Equalization" (also known as "EQ") is the process of adjusting the high or low tones of a given sound.

Most stereo systems (and even TV sets today!) have equalizers built in--even if it's nothing more complicated than a bass or treble control. If you've ever pumped up the bass on your car stereo, you are already familiar with the basic notion of adjusting equalization.

However, most consumer gear only allows you to adjust the equalization as it comes out the speakers--usually you can't adjust the tone of the sound as it being recorded. Professional equipment, on the other hand, does indeed give you this opportunity.

Since this is mostly a function of the post-production process, I won't go into great detail here--all you really need to know at this point is that equalization CAN be adjusted when you record audio. To the right is an example of the impact it can have.
