The outcome of the lesson: Understanding the Equalizer.

Tone Processing: Equalization

Equalization is the process of changing the frequency response of an audio signal, therefore changing its timbre. It is achieved with the use of an equalizer.

Equalizer is:

• An electronic or digital device that processes the frequency response of a signal
• Made up of bands

A band is:

• One change to the frequency response of the processed signal
• Frequency dependant gain control
