Equalisers

Equalisers, or EQs, are tools used in recording studios to adjust the frequency response of an audio signal. Classic EQ units are typically used to cut or boost certain frequencies, allowing the engineer to shape the overall sound of a recording. The frequency bands that an EQ can adjust can vary, but most common EQs feature a low-frequency band, a mid-frequency band, and a high-frequency band. The engineer can adjust the gain of each band to either cut or boost specific frequency ranges in the audio signal.
