i known db convert formula :
20log10 (x/1) = -40dB x = 0.01
0.01 * 223 = 83886.08.
but this formula only use convert single volume control.
my desgin project have many toolbox , i don't know how to get coefficent value.
( have any cookbook for it ? )
1.superbass xover freq, have 36 byte coefficent.( i known value of intenstv and bass gain is direct value ).
2.dynamic bass boost, high threshold(db) and Time constant
( but this db convert is different from singe volume control ?)
3.dynamic bass boost ratio.
4.Surround Sound Volume Control, i don't know how to convert it to coefficent.
