well i hope this understand you
try open winamp or any media player n open the equalizer setting to make it easier to imagine
eq enabled: on ---> as you'll see this must be on
eq precut: 45 ---> its how much louder the sound could be or the preamp (the lower the higher)
eq band 0 cutoff: 50
eq band 1 cutoff: 360 * eq band is the frequencies we will change
eq band 2 cutoff: 1000
eq band 3 cutoff: 4500
eq band 4 cutoff: 14000
eq band 0 q: 6
eq band 1 q: 5 * q is the width of the frequencies above (the lower the wider)
eq band 2 q: 5
eq band 3 q: 8
eq band 4 q: 6
eq band 0 gain: -10
eq band 1 gain: -10 * gain is how much the frequencies we will change (the higher the louder)
eq band 2 gain: -50
eq band 3 gain: 20
eq band 4 gain: 10
good luck then, if you can do by yourself pls share yours here.
thx
