[edit]EQ is the process of using passive or active electronic elements or digital algorithms for the purpose of altering (originally flattening) the frequency response characteristics of a system.[1]
The term generally implies amplitude correction or modification relative to frequency, but any frequency-dependent response characteristic can be equalized. Phase and time-delay methods can be used in equalization. There is also spatial directivity equalization.[2]
