"Equalising" Natural Recordings by Native Speakers
to make something equal or fair by adjusting or compensating for differences or disparities; to bring something into balance or harmony.
Equalizers are devices or controls that are used to adjust the balance of different frequencies in an audio signal, such as the volume of high, mid-range, and low frequencies. They are commonly used in audio equipment, such as amplifiers, speakers, and headphones, to improve the sound quality by enhancing or reducing specific frequencies.
