What do equalizers do

As part of the mixing process, these engineers use audio devices like compressors and equalizers to sound their very best in every audio setup. These audio engineers usually playback the audio through different sets of crappy and HiFi speakers and headphones and make sure the audio is well mixed to sound good on all these different systems.

And as you may already know, audiophiles are purists. They like to listen to music as intended by the artist and the professional audio engineers that mixed and mastered them.

They believe every nuance in a song was meticulously made for a purpose. They want an accurate sound reproduction of the songs they listen to. And using an EQ to boost or cut the bass, midrange, or high frequencies will make the final output inaccurate. Some speakers or headphones have enhanced bass, while others have boosted mids and highs.

This is why every speaker or headphone sounds different. They are all colored. This is something audiophiles want to avoid at all costs. Audiophiles usually spend hundreds and even thousands of dollars on expensive and well-built HiFi speakers or headphones, audio cables, preamp and amps, room acoustics, and more, all in an effort to have a great sounding HiFi audiophile setup, without the need to use an EQ.

Audiophile setups usually sound excellent and bring out the little details in a musical piece. These types use two knobs, one for selecting the frequency and the other to adjust gain. To get more precise control, you can adjust the amount of surrounding frequencies that will be affected. This parameter is called. The higher the Q value, the less surround frequencies will be affected while the lower the Q value, the more surround frequencies will be affected. An EQ will adjust the balance in your audio signal that will allow you to boost or cut certain frequencies, essentially volume control for bass lows , mids or treble highs.

Filters are processors that reduce the volume of specific frequencies of the audio signal. During recording sessions filters are mostly used in order to minimize unwanted noise and sounds in an audio signal.

For example, high-pass filters are commonly used on cymbal and hi-hat microphones in order to minimize sound from the bass drum. Low pass filters are used on low-frequency instruments like bass guitar; it can filter out string buzz or amp hiss. The notch filter would be used to reduce specific noises within the mid-frequency range.

Roll-off refers to how quickly the selected frequency will decline to a non-audible level. The effectiveness of a filters roll-off is measured in the amount of volume they are going to reduce for every octave away from the selected starting point. If a high-pass filter has a 12 dB per octave slope and is set to reduce all frequencies below Hz, that means at Hz one octave below Hz will be reduce by 12dB, 50Hz two octaves below Hz will be reduced by 24dB and 25Hz three octaves below Hz will be reduced by 36dB and so on.

Mostly used to eliminate unwanted low-end rumble. Mostly used to eliminate wanted high-end hiss. In other words, using a high-pass filter and low-pass filter simultaneously. Filters can also be used in a tasteful creative fashion for songwriting or a particular scene of a film. Hot tip : When you make adjustments with EQ, you also affect the overall gain of your signal.

That means extreme EQ settings can change your levels a lot. This control determines the range where boosts or cuts will occur. No matter how tightly you set your Q or how steep you make your slope, an EQ band will always affect a range of frequencies around the target, so be careful. The best way to use EQ is to use it as little as possible. With that in mind, there are two main ways to approach EQ. But if your goal is to use the least EQ, you can simply choose whichever approach is the most direct route to your destination.

For example, if you only need to cut one narrow range, using bands to boost every other region of the spectrum is less transparent that using a single band to cut the main offender.

As a recording engineer, your focus should be to get the sounds you need for your mix as early as possible in the process. Think of everything in terms of the big picture in your mix. Your goal is a polished, professional sound. Every process you apply is just a stepping stone to get there.

Knowing how EQ affects the timbre of your sounds is the key to getting the right parameters for your mix or master. Skip to primary navigation Skip to main content. What is EQ in music?
