I am going to use SOUND command to produce a white noise.

Is there any way to control from the program the volume of the output ?

I want to take a result with max volume and then the volume will decrease to minimum. Something like this |\ |\ |\.

The noise of a steam train engine.

It is here, http://usuaris.tinet.cat/fmco/download/TuShuuu10.asm but i don't know assembly, and here http://usuaris.tinet.cat/fmco/dccfunc_en.html Tushuuu project.

Thank you!
