tone1~ low-budget tone control This low-budget tone control uses coef_hlshelf2~ to provide easy "home stereo style" 3- band graphic EQ for low mid-range and high frequencies. The cut or boost for the three segments is defined in decibels (positive for a boost/gain, and negative for a cut/attenuation). Remember that a signal’s amplitude is doubled when it is boosted by 6 dB and halved when it is attenuated by 6 dB.
