soundgoodizer on the master channe I feel despicable and almost ashamed to be using this plug-in on the master channel. however adding it and changing the knob to around 50% the mix' clarity is just too good to turn back off. 
what im asking is, what does this plug-in actually do and how can I manually go about doing it properly and also better? although the mix sounds better the high-end is also ridiculous and definitely can't be left like that
