Much thanks folks.
I quick looked again at some voices on an audio editor - the levels are way up but acceptably the way CD and DVDs that play clean are. The "middle_ish" main-major body of the voices looked unclipped - so I could see what SWAT_OP R8R meant. Plus I'm skeptical of my gear.
Also quick-easy-lazy tried Audacity audio editor for its preset equalization curves (old EQ curves for LPs). Crashed a couple of times but then even just that took a lot of the edge off. But again I said I'd factor in what SWAT_OP said too, to try to be fair. I copied then tampered separately, left the mod untouched.
If I had to, I'd go with your impression on the raggedness. But try to be open, consider other impressions, takes figuring for with multi opinions. A few sound vocoder-ed or modulated - cool effects, but wasn't sure of harshness. It's cool it runs, anything can be re-tweaked however along or finished it is.
I would submit for consideration new files rather than change mine if online but good point could've easily missed that. Thanks for the touch up and codec advice, probably would've near-missed the codec choice. Used to follow guitar and synth forums, they're handy for record and edit tips but if novice helps to ask for novice advice first.
Thanks much.
