The full name of EQ is Equalizer, EQ is the first two letters of Equalizer, and the Chinese name is "Equalizer".

The more common equalizer is like this:

You can see that this kind of equalizer divides the frequency into several frequency bands. If you move the fader of one of the frequency bands, the frequency will change. the volume of this frequency band.

Okay, let’s talk about it in detail:

First of all, if you don’t have any special preferences in listening to music (for example, you like heavy bass), it is best not to turn on the equalizer, because the music During the mixing stage of the work, the mixer has made the most appropriate and professional equalization adjustment. This equalization adjustment is suitable for most civilian equipment and is also suitable for the current style of music works, such as a rock-style song. For music, the mixer has already made equalization adjustments for the rock style, so there is no need to turn on the rock-style equalization preset on the player, not to mention that such presets are often unreliable.

Secondly, if you have some special preferences in listening to music, but don’t know what each frequency band of the equalizer represents, then introduce it in a more understandable way, using the more common 10-band equalizer. ：

32Hz?——This frequency band requires the playback equipment to have better low-frequency dive ability. If not, of course it will not be easy to hear. This frequency band mainly affects the sustain sound of the kick drum, which is the kick drum. The buzzing sound after the bass drum is played. Enhancing this frequency band can make the music richer.

64Hz?——This frequency band is the main frequency band of the bass drum. If you simply increase this frequency point by 10dB, the most obvious feeling is that the bass drum sound becomes loud or even broken, so enhance this frequency. The frequency band helps the music to be thicker (each adjective is not said casually, it is to let you experience the subjective feeling)

125Hz - This is mainly the frequency band of bass, which is commonly used by bass The timbre of the pitch position is mainly in this frequency band. Of course, this does not mean that this frequency band is only bass. Enhancing this frequency band will make the music more solid.

Basically, if you enhance the above three frequency bands, you will have heavy bass. Let’s talk about the masking effect here. Simply put, for example, if you adjust 125Hz to a very high level, then the frequencies close to 125Hz will be , frequencies with a small dB number will be blocked and cannot be heard.

250Hz - I personally don't like this frequency band too much, whether it is mixing or listening to songs, because I think if there is too much of this frequency band, the sound will be very dirty, and if there is less of this frequency band, the sound will be very clean and hard. , but it is also the frequency band where the main resonance points of vocals, strings, tambourines, etc. are located. You can imagine the rumbling feeling underwater, which is the main feeling this frequency band brings to me.

500Hz - Similar to 250Hz, the enhancement of this frequency band will highlight the tone of some underlying synthesizer pads and make more male voices stand out. If there is too much of this frequency band, it will still be muddy. , increasing it slightly will give the music a more warm, intimate feel.

1000Hz - This frequency band can be regarded as a watershed. The fundamental frequency of most musical instruments is between 200 and 1000Hz, so adjusting the frequency band below 1000 will affect the timbre more (not the volume). Enhance this One frequency band will make the sound brighter.

2000Hz - Enhances the intelligibility of human voices, to put it bluntly, you can hear them more clearly, including the sound of guitar and bass strings rubbing, the sharp feeling of electric guitar, and the advertisements in the loudspeakers of dollar stores. , can allow you to experience more the characteristics of this frequency band, so enhance this frequency band to make the music clearer.

4000Hz - I personally understand that this frequency band is the edge of many sounds, like the frame of a photo frame, the hem of clothes or curtains. Many times this frequency band can make the sound more complete and detailed. , more liveness, but too much improvement will also make people feel harsh and listen to fatigue.

Above 5000Hz is the harmonic component of almost all musical instruments, and it is also the most sensitive frequency band of the human ear. For example, increasing 5000Hz by 6dB will sometimes make people feel that the entire volume has been doubled. If there is too much attenuation, the music will sound Very far.

8000Hz - The most obvious sounds in this frequency band are various cymbal sounds, the sound of strings rubbing against the strings, and sibilance. For example, increasing this frequency band will amplify the singer's four, yes, time, and word one. Class pronunciation. This band is generally rarely boosted significantly.

16000Hz - Well, some people may be young but cannot hear this frequency band. In fact, this frequency band is really difficult to distinguish. If the 16000Hz of a song is increased by 10dB, I will usually listen to it. For various cymbals, the cymbals will appear brighter and louder; conversely, the cymbals will sound smaller and darker. If you don't listen carefully, you will feel that the music has not changed much.
