+## `mbeq split index band_1 band_2 band_3 band_4 band_5 band_6 band_7 band_8 band_9 band_10 band_11 band_12 band_13 band_14 band_15`
+
+In respective order, the band arugments represent the:
+50Hz, 100Hz, 156Hz, 220Hz, 311Hz, 440Hz, 622Hz, 880Hz 1250Hz, 1750Hz, 2500Hz,
+3500Hz, 5000Hz, 10000Hz and 20000Hz frequencies.
+
+All of them represent the band's gain in dB. The range is -70 to +30dB,
+default is 0.
