Audio Filters: Designing an audio equalizer – Part 7
https://www.engineersgarage.com/audio-filters-designing-an-audio-equalizer-7-8/
Equalizers can be designed using audio filters or integrated chips (such as an LA-3600, which is a five-band equalizer IC). For this project, we’ll design a three-band, graphic equalizer circuit using audio filters. So, it will have low, high, and band-pass filter circuits to separate the low, high, and mid-range frequencies of the audio signal.

Design engineers, on the other hand, call this filter parameter Q, which stands for Quality. A typical octave graphic equalizer has a Q of 1 on each of its control bands. Notch filters used for eliminating hum might need a Q as high as 100 if adjacent frequencies are to be left untouched.

Audio filters may be first, second or higher order. First and second order analog filters are generally well understood and their audio uses are somewhat limited, so they are examined briefly. The paper also examines biquadratic filters, or biquads, in more depth because they are more powerful tools for response compensation or EQ.

A filter is a device that passes electric signals at certain frequencies or frequency ranges while preventing the passage of others. — Webster. Filter circuits are used in a wide variety of applications. In the field of telecommunication, band-pass filters are used in the audio frequency range (0 kHz to 20 kHz) for modems and speech processing.
