Thanks for the input and advice!!
Unfortunately, these tracks aren't specimens of oversampling. I have not thought of saturation, wave shaping or exciters, and I don't know a lot about them. If saturation is not an option (it was recorded at 44.1, 16-bit), I will check out the latter.
My latest mix of this track (the one I posted here, but maybe will be replaced soon), I cut down some of the highs and added some mids and lows. Occasionally I notice that a lot of these tracks have painful frequencies. That has been one of my biggest conundrums. With that said, I will also take your eq advice and see what I can do.
After a friend mentioned this to me, I keep thinking about this! I mean, maybe it's worth a try, right?!
Woah cool! Thank you so much....!!!
