The 20 Band Graphic Equalizer
The 20 Band Graphic Equalizer is an IIR based extension of the 10 Band Graphic Equalizer. It exhibits twice the selectivity compared to the 10-band equalizer, since each band is calibrated with half its bandwidth. It is quite useful where greater selectivity is required in order to “tweak” your audio signal frequency distribution, but it is a little more difficult to use compared to the general purpose 10-band equalizer. Its amplification and attenuation range is +/- 12 dB as indicated by the numerical readouts located below each slider control. It has the following frequency band center frequency values:
22Hz, 31Hz, 42Hz, 63Hz, 88Hz, 125Hz, 177Hz, 250Hz, 350Hz, 500Hz, 710Hz, 1.0kHz, 1.4kHz, 2kHz, 2.8kHz, 4kHz, 5.6kHz, 8.0kHz, 11kHz, 16kHz

In all other regards, the 20 Band Graphic Equalizer is operated in the same manner as the 10 Band Graphic Equalizer. Please refer to the description of the Graphic Equalizer above for more details.
Note: All bands above 45 % of the .wav files sampling frequency are disabled.
