In fact, respective FIR design functions of MATLAB or Python design by default symmetric FIR filters, so this means that, with its disadvantages, we can design an audio equalizer with FIR filters without generate a distortion in the signal. For symmetric FIR filters, the group delay is N/2 samples.

Design the filters such that 1000Hz is down by half in each filter (usually, just specifying it as the cutoff is enough.) When you now sum the outputs of the two, they add up to just the audio from 500 to 200Hz, with everything in that range at (more or less) the same amplitude as before.

However, they do not allow control over the shape of the filter for each band. Audio Filters are used to isolate bands, usually in a bell shape around the center frequency. Parametric Equalizers: These are the most frequently used equalizers in high-end home audio systems and in some recording studios as well. The Parametric Equalizer lets you to control the Center Frequency, …

Audio Equalizer. The project implement an audio equalizer in Simulink.it use 5 band pass filter and a low pass filter to filter low frequencies mid range frequencies and high frequency. first low pass filter out frequencies below 125 Hz then band pass filter filter out frequencies between 125 to 250,250 to 750,750 to 2000,2000 to 4000,4000 to 6750,6750 to …

First a 20-band off-line semi-parametric equalizer based on IIR filters using the programming language Delphi is designed. Once the off-line graphic equalizer is implemented, a real time high-performance 20-band parametric equalizer based on FIR or IIR filters using Matlab is aimed.

Use of FIR filters for audio practitioners
https://www.prosoundtraining.com/2016/06/23/fir-filter-audio-practitioners/
Electronic correction in the form of Equalization (EQ) is one of the most useful audio tools for loudspeaker compensation/correction, whether it compensates from non-linearities in the loudspeaker or for altering the effect of room acoustics. Two audio filter types are typically used: IIR and FIR.
