What is an equalizer filter?
An equalizer (EQ) is a type of filter that corrects for losses in the transmission of audio signals, making the output equal to the input, or making an otherwise inconsistent frequency response "flat," giving all frequencies equal energy.
What type of filter are used in graphic equaliser?
Graphic equalizers (like the API 560 graphic EQ pictured below) are simply a collection of fixed-frequency peak/notch filters that can be used to cut or boost several predefined frequency bands at once. Graphic EQs come in various sizes, including 31-band, 15-band, 10-band, 5-band, and even 3-band.
What is the best setting for equalizer?
600 Hz–3,000 Hz (Mids)—the range that humans can hear the best. The majority of the sound of vocals is here, so EQing this range represents the perfect equalizer settings to play with if you want to affect someone's voice. 3,000 Hz–8,000 Hz (Upper Mids)—most audiophiles handle this range with care.
What are the two types of EQ filters?
The filter type determines the general shape of the EQ band. The most common types are high/low pass, bell, notch, and high/low shelf. High-pass (HPF) and low-pass (LPF) filters: These filters are named for the frequencies they leave unaffected, rather than the range they cut.
