ABSTRACT
The term “equalization (EQ),” originates from the formative era of telephone technology. EQ units aimed to make the reception output equal to the transmission signal input. Attenuating or amplifying the kick, bass, or guitars within the 125–300 Hz upper lows can respectively tighten or broaden the impact of the low-end foundation region. Additive EQ within this range can also enhance the fullness of lower-tuned snare drums, rack toms, and vocal vowel sounds. The mids are vital to the natural tonal identity and character of the vast majority of instruments, so less corrective EQ is generally required in this region than in the low-mids. For precise sculpting requirements, parametric EQ tends to be the most powerful and adaptable solution. The sweep EQ technique is an effective way of locating musically desirable areas of the spectrum to amplify, or detrimental frequency regions to attenuate, with the same initial approach for both.
