</div>ok, thats what i want<br>
<br>
perhaps my math is to weak...lol<br>
<br>
I simply will try it out.<br>
<br>
just giving more info: amateur-singer, half an hour of time, lives long<br>
from here. we recorded her voice, but in the lower parts she sang very<br>
quiet, so with normal compression i would compress 95% of what is<br>
correct only to add more gain to those parts. so i thought about this<br>
option instead. probably i should simply elevate volume in those part<br>
instead.<br>
