Also for sound limiter (compressor) algorithms .
Sox has a compander and there is also a Dyson compressor LADSPA plugin.

Here's how I capture speech with ecasound and the Dyson compressor:
ecasound -f:16,2,44100 -i alsahw,0,0 -eca:0,0,0,0 -o capture.wav

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

Yup the LADSPA code comes form the ecasound version of the origninal
Dyson. I dont recommend if for study though, its unusually cryptic.
There are some native LADSPA compressors (SCn) that are easier to follow.
