| Using the EQ during mixing |
 |
|
I have been working on my mixing by reading up on techniques and by a lil bit of trial and error experimenting with different eq's with the software i use to mix. One thing i jus am not understanding is the different numbers of the Hz or Khz on equilizers. The eq's that i have been using, one which is a 7 band eq goes from 63hz to 250hz to 500hz to1500hz to 3khz to 5 to 8. I have another parametric eq that goes from 90 to 250, 500, 1500, 3000, 5000, 8000. Im assuming the lower numbers are for controlling the low frequincy and same with the high numbers with high frequincy. I can hear the changes when i move the knobs but can some one help me understand what the numbers mean and why different eq's have different numbers? |

Sound is a vibrating object, tranfered to our ears through some kind of medium (water air etc), which vibrates our ear drums and we percieve sound.
Objects generally vibrate at regular periodic intervals, and we measure this using the term Hertz, which is its frequency, frequency of oscilation.
1 cycle per second = 1 Hertz, so the frequency of an object vibrating once every second would be 1 Hertz or 1Hz.
Now the ear has a useable range of frequencies it can hear, and that is:
20Hertz to 20Kilo Hertz.
This means the ear cannot detect frequencies lower than 20Hz, nor higher than 20000 Hertz.
Often we just shorten labels and instead of saying 1500 Hertz we just say 1.5KHz.
So if you look at an E.Q. unit you will see the frequency range divided up into equal sections, or equal bandwidths of frequency.
Now you may say why do the numbers increase?
You need to understand that musically one octave is a doubling of frequency, so if we have a note at 120Hz, one octave higher would be 240Hz, one more would be 480Hz and one more would be 960Hz and one more would be 1920Hz.
Sometimes a graphic e.q. unit is divided into 1/3 octaves, which can explain the mysterious nubmers you may see.
So frequency is directly related to pitch, the faster and object vibrates the higher its pitch will be.
Hope that helps.
