"normalise" - in soundforge...

"The Normalize dialog allows you to raise the volume of a selection so that the highest level sample reaches a user-defined level. Use normalization to ensure you are using all of the dynamic range available to you without clipping. To display this dialog, choose Normalize from the Process menu."

i used to use it on normal vinyl recordings, no mixing, so it might do some weired things with a recorded mix (from memory... havent used it for a while, got me levels sorted!)
