Many Tnx
But for beginning i'm looking also for simple physical formulas  
for gain calculation .

Is it RMS  Gain (%) = sqrt (  sum 1..n ( sample[i]^2 )  )  /  MAX_SINE_RMS
or  Gain (%) =  sum 1..n  abs( sample[i] ) /  MAX_SINE_AREA
or something else 

sorre im newbie in sound/DSP programing

Tnx in advance
Ralfs K
