I am having big trouble setting sound levels for my current project. For a particular section I want to increase the sound of the music dramatically for a short section. Judging it by ear I found increasing the sound envelope to the maximum, plus 6.0db of 200% seemed to make hardly any difference on my computer speakers (new) but when played through my A/V club's laptop, projector and sound system it certainly did. It fact all the levels were all over the place but they sound okay on my system.
