What does audio equalization do?
Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer.
How many types of equalization are there?
There are multiple variations of equalizers. Each has a different function, purpose, and characteristic sound. However, the most common types of EQ used in music production are parametric, semi-parametric, dynamic, graphic, and shelving.
What are the two types of equalization?
Parametric Equalizers
Parametric EQs come in two basic variants: semi-parametric and fully-parametric. Fully-parametric EQs include frequency, gain, and Q (bandwidth) controls for each frequency band; low, low-mid, mid, hi-mid, and high, allowing advanced tone shaping capabilities.
What is equalization in audio engineering?
EQ (or equalization) in music is the process of changing the balance of different frequency components in an audio signal. Our ears can detect a huge range of frequencies—roughly 20 Hz to 20 kHz. Each element of your mix has energy in different parts of that range.
